a897e6e229 MIPS: Remove static initializers in v8. 
Port r11010 (1daa81bc).

MIPS-specific changes:
-register codes and registers are defined using a macro to avoid redundancy
-renamed s8_fp to fp, removed the "fp" alias
-removed kSavedValueRegister (found by check-static-initializers.sh)

Original commit message:

Landing for pliard@chromium.org: Remove static initializers in v8.

This change includes two CLs by pliard@chromium.org:

1. http://codereview.chromium.org/9447052/ (Add CallOnce() and simple LazyInstance implementation):

Note that this implementation of LazyInstance does not handle global destructors (i.e. the lazy instances a

This CL was initially reviewed on codereview.appspot.com:
http://codereview.appspot.com/5687064/

2.  http://codereview.chromium.org/9455088/ (Remove static initializers in v8):
This CL depends on CL 9447052 (adding CallOnce and LazyInstance).
It is based on a patch sent by Digit.

With this patch applied, we have only one static initializer left (in atomicops_internals_x86_gcc.cc). This

This CL also modifies the presubmit script to check the number of static initializers.

f14b93a508 Regexp: Improve the speed that we scan for an initial point where a non-anchored 
regexp can match by using a Boyer-Moore-like table.  This is done by identifying
non-greedy non-capturing loops in the nodes that eat any character one at a time.
For example in the middle of the regexp /foo[\s\S]*?bar/ we find such a loop.
There is also such a loop implicitly inserted at the start of any non-anchored
regexp.

When we have found such a loop we look ahead in the nodes to find the set of
characters that can come at given distances.  For example for the regexp
/.?foo/ we know that there are at least 3 characters ahead of us, and the sets
of characters that can occur are [any, [f, o], [o]].  We find a range in the
lookahead info where the set of characters is reasonably constrained.  In our
example this is from index 1 to 2 (0 is not constrained).  We can now look 3
characters ahead and if we don't find one of [f, o] (the union of [f, o] and
[o]) then we can skip forwards by the range size (in this case 2).

For Unicode input strings we do the same, but modulo 128.

We also look at the first string fed to the regexp and use that to get a hint
of the character frequencies in the inputs.  This affects the assessment of
whether the set of characters is 'reasonably constrained'.

We still have the old lookahead mechanism, which uses a wide load of multiple
characters followed by a mask and compare to determine whether a match is
possible at this point.

f00631b710 Reduce initial boot-up memory use. This is an other attempt at what 
http://codereview.chromium.org/9179012 was trying to achieve.  This
time I am going for 80% of the benefit with around 5% of the complexity.

It works by reducing the size of the first page in each space.  Unlike the
previous change there is no attempt to grow pages, we just allocate more
full-sized pages when we need more memory.  For this reason the first pages are
not quite as small (compare
http://codereview.chromium.org/9179012/diff/1/src/snapshot.h with the changes
in spaces.cc in this cl):  We want to be able to do a little bit of allocation
before we have to add a full-sized page to the space.

63f033576c Fix performance regressions due to lazy initialization. 
This CL:
- Adds a new trait parameter to LazyInstance to let it initialize the instance
  without paying the cost of atomic operations (which are expensive on Mac).
  This only works for users who don't care about thread-safety and this is now
the default initialization trait used by LazyInstance in v8.

- Reverts the changes that were made in r11010 in isolate.{cc,h}. That lets
  Isolate's accessors be as cheap as they were before (but adds one static initializer).

- Adds OS::PostSetup() used to initialize the math functions which depend on CPU features.
That lets the math functions get rid of CallOnce().

a3eccef3fa Valgrind cleanliness, part 1: Delete current isolate on exit. 
Currently we leak 140kB from 80 allocation sites when we evaluate a simple
"print(1+2)" in d8 and exit. This might not be a real problem in Chrome because
most of the time the whole process containing v8 vanishes, but it can hide real
leaks in a sea of false positives. Therefore, this CL and a few subsequent ones
clean this up a bit.

This simple CL alone fixes 45 leaks, leaving only 35 with a net loss of 2192
bytes (on ia32).

5bca664574 MIPS: Improve polymorphic loads on single slots. 
Port r11132 (91bdad6108).

Original commit message:

If all property lookups for a polymorphic load actually result in the
same field index under all maps, we can actually emit a monomorphic load
that is guarded by a map check that verifies that the actual map is in
the set of handled maps. This also allows GVN to get rid of redundant
such map checks.

4cb600962f Make setting of accessors even more atomic. 
Now the whole getter/setter/attributes triple gets created/set together,
avoiding any hacks regarding previous values/attributes, making things a lot
simpler.

While doing this, an interesting problem surfaced, which has been there for a
long time: After adding/changing acessors in slow mode, we could potentially
fail going back to fast mode because of a failed memory allocation, signaling
the need for a GC. But we have already changed the object in slow mode, so we
are not idempotent and the retry would trigger a newly inserted assertion
(namely, that the code obeys access restrictions). This has been solved by
splitting the transformation to fast mode from the actual setting of the
accessors.

30a2f2c4ef When running with --always-opt, don't deoptimize named loads with uninitialized type feedback. 
This avoids tests taking too long because of repeated deoptimizations.

b49dd13c90 MIPS: Branch delay slot and other optimizations. 
List of changes:
-added a minor optimization to the Simulator that quickly skips nops in the delay slot
-slightly re-worked CEntryStub to save a few instructions
 CEntryStub now expects the following values:
  -s0: number of arguments including receiver
  -s1: size of arguments excluding receiver
  -s2: pointer to builtin function
 Two new MacroAssembler functions were added to make usage more convenient:
  -PrepareCEntryArgs(int num_args) to set up s0 and s1
  -PrepareCEntryFunction(const ExternalReference&) to set up s2
-removed branch delay slot nops from the most frequently used code areas
-reorganized some code to execute fewer instructions
-utilized the delay slot of most Ret instructions
 This does not cover all Rets, only the most obvious cases.
 Also added a special version of DropAndRet that utilizes the delay slot.
-added some comments to code areas where explanation of the register/delay slot usage may be needed
-added an optimization to Jump so it doesn't always pre-load the target register

64c96ad9c0 There is a trick for speed up array shift operation. 
This trick is confusing a bit the heap snapshoting code.
Such a shiffted array will be interpreted as a new array in the second snapshot.

b0bb4f078a Fix assertion failure due to too many deoptimization ids. 
The failing mozilla test was caused by more deoptimizations
introduced by --always-opt and r11087.

We abort code generation in release mode, so we should do
the same in debug mode.

e081a3bfba Insert explicit deoptimization for named loads that have "uninitialized" type feedback. 
We already do this for binary-ops, unary-ops and comparisons. Typefeedback for named loads can now also
be in "uninitialized" state which means that the corresponding load IC was never executed.

254d810a32 When transitioning LoadIC to megamorphic case place monomorphic stubs into stub cache. 
Otherwise if function is optimized immediately after transition type oracle will be unable to gather enough maps from stub cache and graph builder will emit HLoadNamedGeneric instead of HLoadNamedPolymorphic.
