Add #include <unistd.h> to OProfileWrapper.cpp.   This provides the declarations for 'read' and 'close' that are otherwise missing, and result in 'error: <foo> was not declared in this scope'.

This matches the issue as reported in bug 15055 "Can no longer compile LLVM with --with-oprofile"

Certain vector operations don't vectorize well with the current
PowerPC implementation.  Element insert/extract performs poorly
without VSX support because Altivec requires going through memory.
SREM, UREM, and VSELECT all produce bad scalar code.

There's a lot of work to do for the cost model before
autovectorization will be tuned well, and this is not an attempt to
address the larger problem.

We don't want too many classes in a pass and the classes obscure the details. I

PR15138 was opened because of a segfault in the Bitcode writer.
The actual issue ended up being a bug in APInt where calls to
APInt::getActiveWords returns a bogus value when the APInt value
is 0.  This patch fixes the problem by ensuring that getActiveWords
returns 1 for 0 valued APInts.

These instructions compare two floating point values and return an
integer true (-1) or false (0) value.

When compiling code generated by the Mesa GLSL frontend, the SET*_DX10

A double inclusion will pretty much always be an error in TableGen, so
there's no point going on just to die with "def already defined" or
whatnot.

I'm not too thrilled about the "public: ... private: ..." to expose the
DependenciesMapTy, but I really didn't see a better way to keep that
type centralized. It's a smell that indicates that some refactoring is
needed to make this code more loosely coupled.

This should avoid all bugs of the same nature as PR15189.
