c6e670928d MIPS: Fix mips gyp build for chromium. 
Our planned CL for the Chromium build system passes the toolchain
vars though the Makefiles, so that we do not depend on $CXX, etc.,
in the environment.

That causes a problem with deriving the 'm32flag' in v8 gyp.

This patch lets us build with or without the toolchain vars in
the environment.

be8e8f7528 Improve the JitCodeEventHandler API to add support for line position information. 
This includes:

* adding the CODE_ADD_LINE_POS_INFO, CODE_START_LINE_INFO_RECORDING, CODE_END_LINE_INFO_RECORDING event and the corresponding functionality.
 * adding the JITCodeLineInfo struct to record the code line info. I added this definition because Danno mentioned that "we'd like to cleanup and decouple the external debugging functionality"
 * some other small changes.

250ebdc2be ARM: Change signature for vmov.32 function in the assembler 
The assembler has 8 different vmov variants. The one for vmov.32 and for moving
an immediate into a double reg only differs in the type of the second
paremeter: vmov.32 takes an int, the other takes a double.

The situation is dangerous because C++ will happily implicitly convert between
int and double.

This patch changes the signature of the vmov.32 assembler function so that it
cannot be confused with the other vmovs.

05e95eee0e Allow full inlining of f.apply(this, arguments) calls. 
This allows Crankshaft to completely inline a f.apply() dispatch if the
exact number of arguments is known and the function is constant. The
deoptimizer doesn't generate the f.apply() frame during deoptimization,
so the materialized frames look like f.apply() did a tailcall.
