Revert "[IRGen] Emit lifetime intrinsics around temporary aggregate
argument allocas"
This reverts commit fafc6e4fdf3673dcf557d6c8ae0c0a4bb3184402.
Should fix ppc stage2 failure:
http://lab.llvm.org:8011/builders/clang-ppc64be-linux-multistage/builds/23546
Do you have any more info on the "ppc stage2 failure"? I'd like to pursue
something like this patch to get more accurate lifetime markers for
temporaries, so that LLVM stack slot coloring can do a better job, and we get
smaller stack usage. This is prompted by
