Remembering the current branch is a relic from the past
where no work-dir checkout was used. Now this doesn't give
much benefit and screws up the script if it was left in
a bad state (e.g. after a master restart).

We also cross compile on Windows for example. Since we can't switch the
toolchain there, we'll just use the 64bit toolchain and produce an

Otherwise if function have inferred name then .stack contains it.

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

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.

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.
