Fix PR7272: when inlining through a callsite with byval arguments, the newly created allocas may be used by inlined calls, so these need to have their tail call flags cleared. Fixes PR7272. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@105255 91177308-0d34-0410-b5e6-96231b3b80d8

Fix PR7272 in -tailcallelim instead of the inliner The -tailcallelim pass should be checking if byval or inalloca args can be captured before marking calls as tail calls. This was the real root cause of PR7272. With a better fix in place, revert the inliner change from r105255. The test case it introduced still passes and has been moved to test/Transforms/Inline/byval-tail-call.ll.

Catch more CHECK that can be converted to CHECK-LABEL in Transforms for easier debugging. No functionality change.
