the stricter Error/Expected interface.

If several regions cover the same area of code, we have to restore
the combined value for that area when return from a nested region.
This patch achieves that by combining regions before calling buildSegments.

The root of the problem was that findMainViewFileID(File, Function)
could return some ID for any given file, even though that file
was not the main file for that function.
This patch ensures that the result of this function is conformed
with the result of findMainViewFileID(Function).
This commit reapplies r266436, which was reverted by r266458,

destroy the context (like the global one), no longer now.

Raw function pointer collected by value
profile data may be from external functions
that are not instrumented. They won't have
mapping data to be used by the deserializer.
Force the value to be 0 in this case.

Function names in ObjC can have spaces in them. This interacts poorly
with name compression, which uses spaces to separate PGO names. Fix the
issue by using a different separator and update a test.
I chose "\01" as the separator because 1) it's non-printable, 2) we
strip it from PGO names, and 3) it's the next natural choice once "\00"
is discarded (that one's overloaded).
What's changed since the original commit?
- I fixed up the covmap-V2 binary format tests using a linux VM.
- I weakened the CHECK lines in instrprof-comdat.h to account for the
fact that there have been bugfixes to clang coverage. These will be
fixed up in a follow-up.
- I added an assert to make sure we don't get bitten by this again.
- I constructed the c-general.profraw file without name compression
enabled to appease some bots.

When emitting coverage mappings for functions with local linkage and an
unknown filename, we use "<unknown>:func" for the PGO function name. The
problem is that we don't strip "<unknown>" from the name when loading
coverage data, like we do for other file names. Fix that and add a test.

Patch by Rong Xu
The problem is exposed by intra-module indirect call promotion where
prof symtab is created from module which does not contain all symbols
from the program. With partial symtab, the result needs to be checked
more strictly.
