This patch moves the ownership of profiling state from SILGenProfiling
to SILFunction, where it always belonged. Similarly, it moves ownership
of the profile reader from SILGenModule to SILModule.
The refactor sets us up to fix a few outstanding code coverage bugs and
does away with sad hacks like ProfilerRAII. It also allows us to locally
guarantee that a profile counter increment actually corresponds to the
SILFunction at hand.
That local guarantee causes a bugfix to accidentally fall out of this
refactor: we now set up the profiling state for delayed functions
correctly. Previously, we would set up a ProfilerRAII for the delayed
function, but its counter increment would never be emitted :(. This fix
constitutes the only functional change in this patch -- the rest is NFC.
As a follow-up, I plan on removing some dead code in the profiling
logic and fixing a few naming inconsistencies. I've left that for later
to keep this patch simple.

Changes:
* Terminate all namespaces with the correct closing comment.
* Make sure argument names in comments match the corresponding parameter name.
* Remove redundant get() calls on smart pointers.
* Prefer using "override" or "final" instead of "virtual". Remove "virtual" where appropriate.
Fix a crash in emitBuiltinCall() which occurs because we drop function
linkage information when creating SILCoverageMaps.
This re-applies 45c7e4e86 with the MachO-specific checks in the test
case removed.
If multiple swift files are compiled together, then guessing as to the
file when we emit IR obviously doesn't work. Find the filename when we
generate a function's coverage map and propagate it through SIL.

Keeping a reference to the function here is dangerous. We only
actually care about the name, so save ourselves a copy of that
instead.
This fixes a crash that seems to happen only when the coverage data is
very large.
