[AsmPrinter] Fix placement of function entry comments

The placement is currently wrong in the presence of function entry related
instrumentations (prefixdata, -fpatchable-function-entry=, -fsanitize=kcfi,
etc).

Ensure that prefix data is preserved with subsections-via-symbols

On MachO platforms that use subsections-via-symbols dead code stripping will
drop prefix data. Unfortunately there is no great way to convey the relationship
between a function and its prefix data to the linker. We are forced to use a bit
of a hack: we give the prefix data it’s own symbol, and mark the actual function
entry an .alt_entry.
