7fe1decf3a If there are two consecutive llvm.dbg.stoppoint calls then 
it is likely that the optimizer deleted code in between these
two intrinsics. Keep only the last llvm.dbg.stoppoint in this case.

719b0e17ae CellSPU: Do not custom lower i1 stores, rely on type legalization to do the

Discourage (allocate last) use of x86_64 R12 and R13 due to their
longer instruction encodings.

c738ac1d5d Use %llvmgcc -xassembler instead of invoking as directly. This avoids 
problems for example when LLVM is built with --with-extra-options=-m64
and as defaults to x86-32 mode.

dd643f26c4 Add a utility function that detects whether a loop is guaranteed to be finite. 
Use it to safely handle less-than-or-equals-to exit conditions in loops. These
also occur when the loop exit branch is exit on true because SCEV inverses the
icmp predicate.

Use it again to handle non-zero strides, but only with an unsigned comparison
in the exit condition.
