Since incremental marking hasn't completed yet at this point, we can't
use the MC's root visitor.

Also, we shouldn't hurry with incremental marking while
overapproximating

This fixes some failures on MIPS. Though not all of them, since
MIPS does not correctly implement set_target_internal_reference.

Platform ports that use this RelocInfo kind need to implement
set_target_internal_reference accordingly to distinguish between
INTERNAL_REFERENCE and INTERNAL_REFERENCE_ENCODED.

the lexical variable implementation changed, the inner one is no longer needed.

For ES5 the file names always included the whole path, like this:

  ch15/15.2/15.2.3/15.2.3.14/15.2.3.14-1-3.js

For ES6 this is no longer true:

  language/computed-property-names/basics/symbol.js
  language/computed-property-names/class/method/symbol.js

To allow the status file to correctly identify the right test we need
to change the reported test name to include the whole path.

e8b9f2d7 introduced a different cast which broke building on Illumos.
Revert to previous behavior for V8_OS_SOLARIS only.

Found on SmartOS while building with gcc 4.9.0.

edit1: adding jochen to reviewers since he was assigned through the issue tracker and danno since he seems to do a fair amount of cross-platform work

edit2: removing BUG reference because I don't understand what LOG needs to contain (and it seems to link to chromium and not the v8 repo). Please edit commit message as appropriate.

Cleanup: Better helpers, unified line splitting. Also asserting that without
strong mode, the snippets don't produce errors.

Fix: The eval related tests were wrong (we didn't make sure that the error
thrown comes from strong scoping and is not a normal runtime error).

two inputs, one IfTrue and one IfFalse, which have the same Branch
control input and no other uses except for the Merge. In this case the
