This adds the basics necessary to support float32 operations in TurboFan. The actual functionality required to detect safe float32 operations will be added based on this later. Therefore this does not affect production code except for some cleanup/refactoring. In detail, this patchset contains the following features: - Add support for float32 operations to arm, arm64, ia32 and x64 backends. - Add float32 machine operators. - Add support for float32 constants to simplified lowering. - Handle float32 representation for phis in simplified lowering. In addition, contains the following (related) cleanups: - Fix/unify naming of backend instructions. - Use AVX comparisons when available. - Extend ArchOpcodeField to 9 bits (required for arm64). - Refactor some code duplication in instruction selectors.

Native method invocation from the arm/simulator-arm.cc previously made non-portable assumptions about calling conventions. This was okay for 32-bit stack-based machines, where by-value structs are automatically materialized on the stack, and where both int and double parameters could be passed on the stack. However they are not okay for x86-64, which has an elaborate scheme for passing parameters in registers. This CL replaces the previous non-portable code paths with portable code, using call-sites that accurately match the prototype of the callee.

Add option armeabi to the SCons build for selecting the floating point variant to use. Also add externally defined CCFLAGS environment for all targets. Run test.py with option -S armeabi=hardfloat to test with hardfloat enabled. Make selecting hardfloat EABI variant a build-time option instead of a runtime option. Add a simple check of the EABI variant during V8 initialization to exit if the compilation was not configured correctly. The reason for this is that GCC does not provide a compile time symbol defining the EABI variant. This check is not fool-proof as it cannot check the compilation configuration used for the snapshot if any.

The order of the high/low words of doubles in core register pairs where wrong 2. Missing allocation of a heap number for the result 3.
