df988c7f6b The Array function must be looked up in the native context. 
Platforms x64, a64, arm and mips had the bug that the array function was looked
up in the global context instead of the native context. Fix this, restoring a
weakened assert in hydrogen along the way (by the fix for crbug 347528, which
helped find this case).

94af17a845 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
https://codereview.chromium.org/172753002/ for starting to use it again) and
there were no tests.

3d85b86e23 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
