  Revert "[BasicAA] Remove unneeded special case for malloc/calloc"

This reverts commit 9b1e00738c5ddba681e17e5cb7c260d9afc4c3a7.

Nikic reported in commit thread that I had forgotten history here, and that a) we'd tried this before, and b) had to revert due to an unexpected codegen impact.  Current measurements confirm the same issue still exists.
