This CL fixes all occurences that don't require special OWNER reviews,
or can be reviewed by Michi.

After this one, we should be able to reenable the readability/check
cpplint check.

Instead of creating a new character stream to re-parse the asm.js module,
use the existing stream which was used by the parser.  By doing this, we
avoid accessing the heap if the original character stream is a streaming
source or an external string, which will enable asm.js verification to run
off-thread in those situations.

This fixes the bounds checking of "unsigned" numeric literals (those
that do not contains dots) by the parser. In particular this fixes a
bogus truncation to 32-bit in the scanner. It also makes the scanner
more robust by limiting the range of those numeric literals, hence
completely avoiding rounding loss or truncation errors.

This switches the parser to use token positions (i.e. {Position})
instead of stream positions (i.e. {GetPosition}) everywhere. Access to
the latter is being removed as it is unsupported when the scanner is in
rewind state anyways. This prevents "skipping" a token when seeking.

Adding a custom lexer for asm.js parsing.
It takes advantage of a number of asm.js properties to simply things:
* Assumes 'use asm' is the only string.
* Does not handle unicode for now (tools don't emit it).
* Combines global + local string table with lexer.
