Original commit message:

This caches call targets of constructor calls by associating one element
caches with call sites. The type feedback oracle can use the recorded
valued to gather type information for monomorphic constructor call sites.

1) Don't make a call to C without having a valid frame on the stack.
2) Don't generate a call to a stub while generating a stub, unless we can be
sure that the stub we are calling has already been generated (the stub
generation code is not reentrant wrt. GC).

Make mips-specifc changes for r7999, r8001, r8002.

Also bring in changes for older commits 7203, 7279, 7693, 7715, 7788.

Mips changes for 7715 (Arm: Support hardfloat in SCons build), and
7693 (Implement hardfloat calling convention in macro assembler and simulator)
resulted in changes to SConstruct.

- Merge to current tip of tree, fix build problems.
- Remove deprecated source files.
- Add cctest test-disasm-mips
- Consistently use single-reg push()/pop() (remove uppercase variants)
- Add assembler field accessors.
- More style fixes.

This commit adds current working versions of assembler, macro-assembler,
disassembler, and simulator.

All other mips arch files are replaced with stubbed-out versions that
will build.

Arch independent files are updated as needed to support building and
running mips.

The only test is cctest/test-assembler-mips, and this passes on the
simulator and on mips hardware.

Chromium build.

v8.gyp no longer sets any V8_TARGET_ARCH_* macro on the Mac. Instead, the
proper V8_TARGET_ARCH_* macro will be set by src/globals.h in the same way as
the V8_HOST_ARCH_* macro when it detects that no target macro is currently
defined. The Mac build will attempt to compile all ia32 and x86_64 .cc files.
#ifdef guards in each of these target-specific source files prevent their
compilation when the associated target is not selected. For completeness,
these #ifdef guards are also provided for the arm and mips .cc files.

This is the first step in the MIPS port of V8. It adds assembler, disassembler and simulator for the MIPS32 architecture.

Contains stubbed out implementation of all the compiler/code generator infrastructure to make it all build.

This change adds a post-order numbering to AST nodes that
are relevant for the fast code generator. It is only invoked
together with the fast compiler. 

Also changed the ast printer to print the  numbering for 
testing purposes if it is present.

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.
