[PATCH] D85614: [TRE] Reland: allow TRE for non-capturing calls.

[Alexey Lapshin via Phabricator via llvm-commits]

avl updated this revision to Diff 297566.
avl added a comment.

Implemented that algorithm: First, create a temporary alloca 
corresponding to each byval argument. Then, copy each byval
argument to the call to its temporary alloca. Finally, copy
each byval argument to the call from the temporaries to the
memory originally allocated for the function's arguments.
