Re-apply "[profiling] Remove dead profile name vars after emitting name data"
This reverts 295092 (re-applies 295084), with a fix for dangling
references from the array of coverage names passed down from frontends.
I missed this in my initial testing because I only checked test/Profile,
and not test/CoverageMapping as well.
Original commit message:
The profile name variables passed to counter increment intrinsics are dead
after we emit the finalized name data in __llvm_prf_nm. However, we neglect to
erase these name variables. This causes huge size increases in the
__TEXT,__const section as well as slowdowns when linker dead stripping is
disabled. Some affected projects are so massive that they fail to link on
Darwin, because only the small code model is supported.
Fix the issue by throwing away the name constants as soon as we're done with
them.
