[PATCH] D65019: [ARM] push LR before __gnu_mcount_nc

[Eli Friedman via Phabricator via cfe-commits]

Yes, it's technically a "call", but you don't need the call lowering code.  That's dedicated to stuff like passing arguments, returning values, checking whether the function can be tail-called, etc.  None of that applies here; the intrinsic always corresponds to exactly one pseudo-instruction, a BL_PUSHLR.
