76ac8bc73b Removed static type inference and add a dynamic test for string addition. 
The complexity of static type inference never really paid off, and as an
analysis it didn't fit well with codegen frame propagation.

ce7cdbd799 Change the implementation of Math.random to use George 
Marsaglia's multiply-with-carry instead of mixing the
bits obtained from calling the system random() twice.

This seems to be a bit faster and gives a better

b7d48f5807 A bunch of changes to speed up math on ARM. 
* Identify heap numbers that contain non-Smi int32s and do bit
ops on them without calling the fp hardware or emulation.
* Identify results that are non-Smi int32s and write them into
heap numbers without calling the fp hardware or emulation.
* Do unary minus on heap numbers without going into the runtime
system.
* On add, sub and mul if we have both Smi and heapnumber inputs
to the same operation then convert the Smi to a double and do
the op without going into runtime system.  This also applies
if we have two Smi inputs but the result is not Smi.

6b2a49ff83 * Modify simulator and ARM code generator to avoid swi 
instructions.  The intention is that the snapshots generated
by the simulator should be usable on the hardware.  Instead of
swi instructions we generate a branch to a swi instruction that
is not part of the snapshot.  The call/jump is patched up in
the same way as other external references when the snapshot
is deserialized.  This only works for EABI targets: on old ABI
targets we still emit some instructions not supported by the
simulator (fp coprocessor instructions).

bd82b972fc Simplify the processing of deferred code in the code generator. Our 
deferred code snippets are highly stylized.  They always make a call
to a stub or the runtime and then return.  This change takes advantage
of that.

Creating a deferred code object now captures a snapshot of the
registers in the virtual frame.  The registers are automatically saved
on entry to the deferred code and restored on exit.

The clients of deferred code must ensure that there is no change to
the registers in the virtual frame (eg, by allocating which can cause
spilling) or to the stack pointer.  That is currently the case.

As a separate change, I will add either code to verify this constraint
or else code to forbid any frame effect.

The deferred code itself does not use the virtual frame or register
allocator (or even the code generator).  It is raw macro assembler
code.

01f7c87f22 This patch much improves our tracking of whether function is 
called from within a loop or not.  In the past we lost the
information if a call site went megamorphic before a lazily
compiled callee was called for the first time.  Now we track
that correctly (this is an issue that affects richards).
We still don't manage to track the in-loop state through a
constructor call, since constructor calls use LoadICs instead
of CallICs.  This issue affects delta-blue.  So in this patch
we assume that lazy compilations that don't happen through a
CallIC happen from inside a loop.  I have an idea to fix this
but this patch is big enough already.
With our improved tracking of in-loop state I have switched
off the inlining of in-object loads for code that is not in
a loop.  This benefits compile speed.  One issue is that
eagerly compiled code now doesn't get the in-object loads
inlined.  We need to eagerly compile less code to fix this.

30a0a7de43 Split nested namespaces declaration in two lines in accordance with C++ Style Guide. 
This issue was raised by Brett Wilson while reviewing my changelist for readability. Craig Silverstein (one of C++ SG maintainers) confirmed that we should declare one namespace per line. Our way of namespaces closing seems not violating style guides (there is no clear agreement on it), so I left it intact.

bcab3697f6 Simplify JumpTarget::ComputeEntryFrame. Eliminate a separate pass 
over the frame elements to find registers used (before allocating
undetermined elements) and another pass to set the frame's register
indices (after allocating all elements).

To re-enable tests, instead of compiled code patching, inlined code is used.
Inlined code is only installed in test.

7adff828a0 Port change (r1837) that allows call-as-function handlers to be called 
through new to ARM.  

Added simple test case of the current behavior.

For consistency, changed a number of occurences of explicit moves to
pc to use Jump instead.

cc0c8d178f Materializing a frame element on the stack by pushing it can cause the 
stack pointer to change by more than one in a corner case.  If we push
a constant smi larger than 16 bits, we push it via a temporary
register.  Allocating the temporary can cause a register to be spilled
from the frame somewhere above the stack pointer.

As a fix, do not use pushes to materialize ranges of elements of size
larger than one.
