Work around a gcc 4.6.3 / 4.7 bug.
GCC bug http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58416
causes the bf64-1.c test to fail in the GCC torture test suite.
This provides an upstreamable workaround.
Inspection of the LLVM code base showed no other instances of
the pattern that triggers the gcc bug.
This can also be upstreamed as soon as I can get a working
x86-32 upstream build working to verify/test against. In the
meantime, we can make one pnacl-fyi bot go green again.
