b09ac9d7ec Use the correct for for the version. It's little endian and my brain is 
obviously big endian. :-)

c4ab50bd33 move tier out of an anonymous namespace, it doesn't make sense

ba37b6516a indvars: LinearFunctionTestReplace for non-canonical IVs. 
For -disable-iv-rewrite, perform LFTR without generating a new
"canonical" induction variable. Instead find the "best" existing
induction variable for use in the loop exit test and compute the final
value of that IV for use in the new loop exit test. In short,
convert to a simple eq/ne exit test as long as it's cheap to do so.

111d0bc134 indvars: Added isHighCostExpansion. Avoid generating extra ops in the 
preheader for the sole purpose of LFTR, since LFTR itself is usually not
a clear optimization.

bdf65ac132 Disable loop idiom recognition of memset/memcpy if the function being compiled 
is named after a common idiom (i.e., memset/memcpy).  Otherwise, we can run into 
infinite recursion.  Ideally, the user should use the correct -fno-builtin flag,
but in case they don't we should play nicely.
