Chris Lattner 80ed9dc9e5 rip out a ton of intrinsic modernization logic from AutoUpgrade.cpp, which is 
for pre-2.9 bitcode files.  We keep x86 unaligned loads, movnt, crc32, and the
target indep prefetch change.

As usual, updating the testsuite is a PITA.

Eric Christopher da2d2f4d1f Experiment with changing the default 32-bit linux stack alignment to 
16 bytes for PR8969. Update all testcases accordingly.

Chris Lattner 38461f6b2f Fix a nasty miscompilation of 176.gcc on linux/x86 where we synthesized 
a memset using 16-byte XMM stores, but where the stack realignment code
didn't work.  Until it does (PR2962) disable use of xmm regs in memcpy
and memset formation for linux and other targets with insufficiently
aligned stacks.

This is part of PR2888
