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.

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.
