MIPS: Fix KeyedStoreStubCompiler::GenerateStoreFastDoubleElement()
...
Test regress-91013.js (to ensure that the stored value was returned) passed on mips
without this fix, since the input value (in value_reg, a0) also happens to be in
mips return value register v0 at the time of call.
But it is fragile to depend on that behavior, so an explicit move from a0 to v0
is warranted. This fix puts that move in the delay slot of the Ret().

Passing a value of type Executability to a function expecting a bool worked only
by accident (because of the order of values in the enum). But using boolean
parameters is often a bad idea, anyway, so we use Executability directly.

Do not use deprecated ARM instructions in DirectCEntryStub::GenerateCall.
...
Non-ancient versions of the ARM-ARM explicitly deprecate most uses of the PC
within instructions and older ARM implementations have a non-predictable offset
(8 or 12) for some of these deprecated uses. Avoiding the deprecated instruction
costs us one additional instruction in DirectCEntryStub::GenerateCall, but this
should not cause any significant performance degradation.
The deoptimizer still uses the PC in a stm instruction, but it is a bit unclear
what to do about that, so simply a comment has been added to reconsider this in
the future.

Simplify and optimize ToBoolean handling.
...
Changing our builtin JavaScript code slightly, we can make sure that we never
see internal objects as arguments for ToBoolean at runtime. Removing that case
from the stub generator and crankshaft makes things a lot easier.
Heap numbers can never be undetectable (only strings and spec objects can), so
we can leave out a useless test.
Try to re-use a non-null register value when returning 'true' in some cases.
Removed special handling of the 'handle all' case, it will very probably never
happen in real code and only makes things more complicated.
Improved naming of the ToBoolean stubs a bit, reflecting the order in which
cases are handled in the code itself.

* Bug fix for range analysis (contributed by Andy Wingo). Ranges of
double values have to include negative zero. Original code review:
http://codereview.chromium.org/7514040/
* Fix a bug in optimized Math.round on ARM. When emitting minus-zero checks
we previously return a wrong result because of incorrect register assignment.
* Fix performance problem in IA32 and x64. Refine the checks
for minus zero and avoid unnecessary deoptimizations on Math.floor.
* Improve mjsunit test for Math.round to make sure we also
get the optimized version of the code for each test case.

Fix a bug in scope analysis.
...
When recompiling code (e.g., when optimizing) we could incorrectly hoist
some function expressions. This leads to incorrect results or a crash. The
root cause was that functions were not correctly categorized as expression
or declaration at parse time.
This requires some extra hoops to prevent the print name "anonymous" for
functions created by 'new Function' from establishing a binding.

Revert "Revert "Fix a bug in scope analysis.""
...
Reapply r8783 with an additional fix.
Because the preparser and parser do not use the same scope analysis to
determine if a function can be lazily compiled, the parser can have false
positives. Rather than treating this as a parse error, treat the preparser
as authoritative and eagerly compile the function.

Use type info for the ToBoolean translation in crankshaft.
...
To do this, the Branch instruction needs to carry around a temporary register,
but only when the crankshafted code will make a map access. When the
crankshafted code sees an object of a type it hasn't encountered before, it will
always trigger a deopt. Another option in theses cases would be calling a
ToBooleanStub which can handle all types, but then one has to be careful to
*not* trigger a GC (which is currently a bit tricky to achieve).
Const-corrected ToBoolean::Types. Moved the NeedsMap logic into ToBoolean::Types
itself, where it belongs.
This patch improves a lot of benchmarks, crypto-orig even by 16.7%, but slows
down others. The slowdown has to be investigated, but I'd like to get this patch
out first to fix the flakiness problems we currently have due to the previous
crankshafted ToBoolean.

Do not explicitly record undetectable objects in the ToBoolean stub.
...
Loading the map within the stub already implies a check for an undetectable
object, so there is no need to record this separately. Furthermore, this brings
the size of the type info to record down to 8 bits, removing the need to find a
place for the ninth bit in the Code object. ;-)

Implement a type recording ToBoolean IC.
...
The IC records the set of types it has seen, e.g. {String} or {Boolean,
Undefined}, etc. Note that in theory this could lead to a large number of
different ToBoolean ICs (512, to be exact, because we distinguish 9 types),
but in practice only a small handful of them are actually generated.
Currently the type recording part is only implemented on ia32, other platforms
continue to work like they did before, though.
Removed some dead code on the way.

- 32-bit Linux already seems to scatter the mmap() chunks around;
64-bit didn't.
