dupe_error_loc vs dupe_loc) are now consistently named the shorter way.

These comparisons are only meant to be done by AstValueFactory itself (in
its string_table_ operations), so make the Compare() function a private
member of AstValueFactory.
All other clients of AstRawStrings should compare them by pointer value.
There were only two clients which failed to abide by this rule, one
recently-added (in ModuleDescriptor) and the other in Literal::Match
(in ast.cc, added in https://code.google.com/p/v8/source/detail?r=24396).

- drop ConvertTo, replace it with simple copy
- split AllocatedOperand off from Immediate and Constant to make assignment clearer, also paving the way for small Immediates

This allows loopy TurboFan code to be interrupted by placing a stack
check (i.e. JSStackCheck node) into each loop. Note that we currently
limit this to non-asm.js code. Also note that stack checks are actually
placed after loop headers and not at back-branches, which allows us to
reuse existing BailoutIds from Crankshaft.

This is a follow-up to 2d281e71ac and prevents bailouts on empty
script contexts in Crankshaft, which don't need allocation. Only
non-empty script contexts should cause a bailout.

Performance measurements show that the position independent code is
usually slightly faster than the position dependent code, and there
seems to be no noticable regression.
This also gets rid of a lot of support code that was only required to allow
embedding labels into the code stream. And it implies that neither the GC
nor the deserializer need to do anything for jump tables.

We can use xorps/xorpd on Intel CPUs to flip the sign bit. Ideally we'd
use a RIP-relative 128-bit constant in the code object, as OCaml/GCC
does, however that requires 128-bit alignment for code objects, which is
not yet implemented. So for now we materialize the mask inline.

Previously, the only optimized code path for Maps and Sets was for String keys.
This was achieved through an implementation of various complex operations
in Hydrogen. This approach was neither scalable nor forward-compatible.
This patch adds the necessary intrinsics to implement Maps and Sets almost entirely
in JS. The added intrinsics are:
%_FixedArrayGet
%_FixedArraySet
%_TheHole
%_JSCollectionGetTable
%_StringGetRawHashField
With these additions, as well as a few changes to what's exposed as runtime functions,
most of the C++ code backing Maps and Sets is gone (including both runtime code in
objects.cc and Crankshaft in hydrogen.cc).
