069d783a91 Remove the PreCompile API and ScriptData. 
The new compilation API (ScriptCompiler::Compile) can produce the same data, so
the separate precompilation phase is not needed. ScriptData is replaced by
ScriptCompiler::CachedData.

ff953ac055 Make maps in monomorphic IC stubs weak. 
Maps in monomorphic Load, KeyedLoad, Store, KeyedStore, and CompareNil IC
stubs are treated as weak references by the marking visitor.

During generation of an IC stub with a weak map, the stub is appended to the
dependent code array of the map. When the map dies, all stubs in its dependent
code array are invalidated by setting embedded maps to undefined.

b61696dd95 ARM: Do not set FPSCR when converting to clamped uint8 
Setting the FPSCR flags is expensive on some CPUs. Get rid of repeated
setting of the FPSCR by relying on the correct default flags being set
when doing uint8 clamping. Also use vcvt_u32_f64 instead of vcvt_s32_f64,
which enables removing the check against zero (vcvt_u32_f64 will clamp to
zero).

To be on the safe side, add asserts to check that the VFP rounding mode
flags are set to default as expected.

This increases performance of a hot loop repeatedly setting
Uint8ClampedArray values on some CPUs by as much as a factor of 12.

74d49a1e7e ARM64: Preserve x8 and x9 when necessary. 
Fix a couple of places were x8 and x9 are excluded from lists of saved
registers. These are caller-saved registers, so C code can corrupt them.

x8 and x9 were originally reserved for debug code in the ARM64 port, so
we didn't bother preserving them, but they are now normal allocatable
registers.

b88068ff2b Add support for --raw and --omit to js2c. 
--raw writes the raw source data to a separate file
  --omit allows omitting the source data from the generated files.

The intention is (future) support for having the embedder optionally
store the source data 'blob' and handling it to V8::Initialize, with
the goal of reducing the binary size of V8.

The patch also contains numerous unrelated changes/refactorings in the hope of increasing maintainability. Let me know whether you agree. In particular:
- Remove some unused code.
- Do not overwrite Python built-ins (e.g. the type() function)
- Do not use a string as exception object (no longer supported in python 2.7)
- Add command line argument handling + help text.
- Split logic into:
  - PrepareSources - which reads + preprocesses the source files
  - BuildMetadata - which takes the prepared sources and generates the data the code template needs.
