Clear optimized code cache in shared function info when code gets deoptimized.
This adds a pointer to the shared function info into deoptimization data of an optimized code. Whenever the code is deoptimized, it clears the cache in the shared function info.
This fixes the problem when the optimized function dies in new space GC before the code is deoptimized due to code dependency and before the optimized code cache is cleared in old space GC (see mjsunit/regress/regress-343609.js).

We already have code that expects this, but incorrectly asserted that the
filler map case would never happen when allocation folding is turned on.
However, even folding has it's limits, bailing out of continued folding
when the object size grows too large. Therefore, it's a general problem

Fix the bit massaging code in CompleteParserRecorder::WriteNumber.
The original code, added by
https://codereview.chromium.org/3384003/diff/7001/src/parser.cc 3.5 years ago,
failed to write numbers which contain a chunk of 7 zeroes in the middle. The
smallest such number is 2^14, so this is a problem if the source file to
preparse contains 16384 or more symbols (which happens in the wild).
This bug went unnoticed because the symbol data was not used by Parser (see

Lazy preparsing vs. lazy parsing fix.
Preparsing is always maximally lazy (every function that can be lazy is preparsed
lazily), but Parser has more complicated laziness logic.
If we're going to parse eagerly, and we have preparse data from lazy preparsing,
we're gonna have a bad time. The symbol stream won't contain symbols inside lazy
functions, and when the Parser parses them eagerly, it will consume symbols from
the symbol stream, and everything will go wrong.
This bug was hidden because the symbol cache was not used for real (see

Refactoring: Extract low-level git from push and merge scripts.
- This adds a python layer on top of the low-level git calls to control parameter passing and return values.
- This also fixes a bug in FindLastTrunkPush that only shows up in manual mode when the last push versions are iterated.
- The order of some parameters changed in some git calls in the tests to be uniform.

Re-enable Parser::symbol_cache_ (after a long time!)
The Parser never used the symbol stream produced by the PreParser for anything
useful, due to a bug introduced 3.5 years ago by
https://codereview.chromium.org/3356010/diff/7001/src/parser.cc.
The bug is that calling Initialize on symbol_cache_ doesn't change its
length. So the length remains 0, and the "if" in Parser::LookupSymbol is always
true, and Parser::LookupCachedSymbol is never called and symbol_cache_ never
filled.
This bug also masked a bug that the symbol stream produced by PreParser doesn't
match what Parser wants to consume. The repro case is the following:
var myo = {if: 4}; print(myo.if);
PreParser doesn't log a symbol for the first "if", but in the corresponding
place, Parser consumes one symbol from the symbol stream. Since the consumed
symbols were never really used, this mismatch went unnoticed.
This CL also fixes that bug.
