This also changes modulo to be more like others, e.g., Pow:
- have an inline Modulo
- have a modulo_double_double that we can use as FUNCTION_ADDR in assembler.cc

Don't hold a pointer to parse_info in compilation_info, and instead explicitly
add the fields needed in compiation_info. The intention is to make ParseInfo
only actually needed for parsing, and eventually make it possible to compile
with only a CompileInfo.

This CL introduces TurboAssembler, a super-class of Assembler and sub-class
of MacroAssembler. TurboAssembler contains all the functionality that is used
by Turbofan and previously was part of MacroAssembler. TurboAssembler has
access to the isolate but, in contrast to MacroAssembler, does not expect to
be running on the main thread.

Also, CodeGenerator::MakeCodeEpilogue now accepts an optional pointer
to a EhFrameWriter and will attach unwinding information to the code
object when passed one.
Reason for reverting:
The STATIC_CONST_MEMBER_DEFINITION in eh-frame-writer-unittest.cc
causes a compiler error on V8 Win64 - clang buildbot.
Removing that bit.

Import base::ieee754::exp() from FreeBSD msun and introduce a Float64Exp
TurboFan operator based on that, similar to what we do for Float64Log.
Rewrite Math.exp() as TurboFan builtin and use that operator to also
inline Math.exp() into optimized TurboFan functions.

Each Script object now keeps a WeakFixedArray of SharedFunctionInfo
objects created from this script.
This way, when compiling a function, we do not create duplicate shared
function info objects when recompiling with either compiler.
This fixes a class of issues in the debugger, where we set break points
on one shared function info, but functions from duplicate shared function
infos are not affected.
