672f5ffab6 Port lithium template classes to ARM. 
This is a port of the IA32 version and is needed to allow 
changing the register allocator interface in a later change.

8a1416c78d Fix double allocation of register on arm in DoDeferredMathAbsTaggedHeapNumber. 
This should fix the sputnik issue on the arm simulator.

Priorly tmp2 and tmp3 could potentially be the same register as input.

cbc1c0fca6 Truncate rather than round to nearest when performing float-to-integer 
conversions for external array types, which implement the Typed Array
spec. (Revision of http://codereview.chromium.org/6315004 .)

Prefer SSE2 code path on x86 processors. Non-SSE2 processors now make
a slow runtime call for float-to-int conversions. Use SSE3 for 32-bit
signed and unsigned int array types where possible.

The movement of code from ic-arm.cc to stub-cache-arm.cc caused the
VFP3 code path to be tested for the first time. Fixed bugs in the
register usage and in the constant value stored into integer arrays
for NaN and +/-Infinity.

Added new truncation test to test-api.cc. Storage of NaN and +/-Inf
was already covered. Ran unit tests on x86, x64 and ARM simulator.
Tested ia32 and x64 code in Chromium on Mac and Linux respectively
with Typed Array unit tests and WebGL content.

8a9eeaf8da Reapply change to with/arguments interaction. 
This is svn r6415 with a bugfix.

The bug was that we can have scopes with 0 heap slots (functions with
such scopes do not need a local context) and scopes with at least
Context::MIN_CONTEXT_SLOTS.  The code generator only allocated a local
context if there were strictly more than Context::MIN_CONTEXT_SLOTS.
Before the change to with/arguments, it was impossible to actually get
a function scope with exactly Context::MIN_CONTEXT_SLOTS because every
such scope included a heap-allocated arguments (and arguments shadow)
slot.

7f43cf0539 Make 'with' mark only variables occurring in the body as used. 
Before, we conservatively marked every variable in a scope as used if the
scope contained 'with'.  Instead, just mark the variables occurring in the
body of the with.  This avoids marking 'arguments' as used whenever 'with'
occurs, which incurs an extra performance penalty (a use of arguments is
seen as an instruction to redirect all parameter accesses to the arguments
object).

b4ff318e4b Support StringCharCodeAt in hydrogen/lithium. 
This patch adds H- and L-variants of StringCharCodeAt and StringLength.

StringCharCodeAt is used to inline a constant function call of
String.prototype.charCodeAt and to implement the corresponding inline
runtime function. It does not yet use the recently introduced extra IC
state. (We can specialize on string encoding and avoid deopts because
of out of bounds accesses.)

StringLength needs more work because the stub version of it also
supports strings wrappers and it matters in some cases. (We have to
separate the string only case.)

We hit an assertion failure when we tried to record the AST ID of
the (shared) .arguments variable proxy more than once.  This was hit
when we had multiple calls to the same parameter in a function that
used the arguments object.  The fix is to not visit the subexpressions
of the (shared) property access expression.
