[google] Merged trunk -> google/integration

[Diego Novillo <dnovillo at google dot com>]

This merge switches google/integration back to trunk.  Several
things needed adjusting.

I added 4 patches:

- Fix redirection for TEST_ALWAYS_FLAGS.  Trunk is now using
  site.tmp instead of tmp0 (thanks cgd for spotting this one).

- XFAIL an -flto bug when using gold.  This happens in
  builtins/strstr-asm.c.  Somehow, LTO fails to declare my_strstr
  causing a linker error.  Cary did some analysis on it and
  concluded that GCC was not presenting this symbol to the
  plugin, so this is a bug in LTO.  Honza, does this ring a bell
  to you?

- tree-ssa/vrp47.c is also failing in trunk.  XFAIL'd.

- gfortran.dg/coarray_lock_3.f90 has been fixed in trunk, but
  after this merge.  I've removed the expected error message.

- libmudflap.c++/pass55-frag.cxx is flaky under GRTE.  It would
  sometimes fail and sometimes run fine.  I've XFAIL'd it.

- libmudflap.c/pass-stratcliff.c was producing pre-processor
  warnings.  This has been fixed in mainline by rewriting the
  test.  We'll pick it up in the next merge.  For now I simply
  fixed the erroneous line.

- libmudflap.c/pass49-frag.c now works, so I removed the XFAIL.

- libstdc++/testsuite/23_containers/vector/requirements/dr438/*:
  still fail but the error lines have shifted.  Adjusted them.

- The next two are somewhat odd.  We build the 32 bit toolchain
  with default -mtune=pentium4.  This causes a failure in
  pr27827.c because we do not find the expected assembly.  I
  forced -mtune=generic to fix that.  I also got flaky behaviour
  from i386/sse4_1-blendps.c, so I forced it to compile with -O0.
  I think it's related to GRTE as well, but I'm not positive.

With these changes, the trunk validates on x86_64.
