Folding IntToPtr or PtrToInt into Loads, due to r238452,
perturbs the mips-varargs test-case.
Patch by Philip Pfaffe!
Differential Revision: http://reviews.llvm.org/D9153
llvm-svn: 238455
Summary:
The Mips ABI's treat pointers in the same way as integers. They are
sign-extended to 32-bit for O32, and 64-bit for N32/N64. This doesn't matter
for O32 and N64 where pointers are already the correct width but it does matter
for big-endian N32, where pointers are 32-bit and need promoting.
The caller side is already passing pointers correctly. This patch corrects the
callee.

This reverts commit r222144. Commit r222142 is being reverted due to
a spec2006/gcc execution-time regression.
Update mips-varargs test as well.

Summary:
With this patch, passing a va_list to another function and reading 10 int's from
it works correctly on a big-endian target.
Based on a pair of patches by David Chisnall, one of which I've reworked
for the current trunk.

Summary:
Vectors are normally 16-byte aligned, however the O32 ABI enforces a
maximum alignment of 8-bytes since the base of the stack is 8-byte aligned.
Previously, this was enforced on the caller side, but not on the callee side.
This fixes the output of OpenCL's printf when given vectors.
