Add X86 feature detection support for BMI instructions. Added new cpuid function for accessing leafs with sub leafs specified in ECX. Also added code to keep track of the max cpuid level supported in both basic and extended leaves and qualified the existing cpuid calls and the new call to leaf 7.

Add a bad char heuristic to StringRef::find.

Based on Horspool's simplified version of Boyer-Moore. We use a constant-sized table of

Fix indvars randomness by removing iteration over a map.
...
I rewrote the algorithm a while back so it doesn't require map lookup,
but neglected to change the data structure. This was caught by
llvm-gcc self host, not because there's anything special about
llvm-gcc, but because it is the only test for nondeterminism we
currently have. Unit tests don't work well for everything; we should
always try to have a nondeterminism stress test running.

Mark tADDrSPi as having side effects again.

It really doesn't, but when r141929 removed the hasSideEffects flag from
this instruction, it caused miscompilations. I am guessing that it got
moved across a stack pointer update.
Also clear isRematerializable after checking that this instruction is
in fact never rematerialized in the nightly test suite.

Thumb1 does not support dynamic stack realignment.

rdar://10288916 is tracking this fix.
In the past, instcombine and other passes were promoting alloca alignment past
the natural alignment, resulting in dynamic stack realignment. Lang's work now
prevents this from happening (LLVM commit r141599). Now that this really
shouldn't happen report a fatal error rather than silently generate bad code.
