John McCall	4f54c75dc8	Use Clang's logic for adding the default IR attributes to a function. ... A lot of attributes are essentially default target configuration, and we should only differ when there's a good reason to. For the attributes we were already setting: - the ptrauth and target CPU/feature attributes are taken care of by Clang - I've updated the optsize/minsize attributes to the apparent intent - I've left the frame-pointer override in place for now Fixes rdar://63289339, which was caused by Swift's ptrauth IR attributes getting out of sync with Clang's.	2020-05-21 02:24:20 -04:00
