This is a re-try of r295085: fix up some test cases that assume that
profile name variables are preserved by the instrprof pass.
This catches one additional case in test/CoverageMapping/unused_names.c.

Temporarily relax check in test to avoid
breakage for format change in LLVM side. Once that is
done, the test case will be retightened.

This patch changes cc1 option -fprofile-instr-generate to an enum option
-fprofile-instrument={clang|none}. It also changes cc1 options
-fprofile-instr-generate= to -fprofile-instrument-path=.
The driver level option -fprofile-instr-generate and -fprofile-instr-generate=
remain intact. This change will pave the way to integrate new PGO
instrumentation in IR level.

(test case update)
Profile symbols have long prefixes which waste space and creating pressure for linker.
This patch shortens the prefixes to minimal length without losing verbosity.

(This is part-2 of the patch -- fixing test cases)
Before the patch, -fprofile-instr-generate compile will fail
if no integrated-as is specified when the file contains
any static functions (the -S output is also invalid).
This patch fixed the issue. With the change, the index format
version will be bumped up by 1. Backward compatibility is
preserved with this change.

We try to use the member variable "FuncName" here, but we've also used
that name as a parameter. This ends with us getting the length of the
function name wrong when we generate the coverage data.

This is a test for the llvm change in r228793. We need to make sure
that names referred to by coverage end up in the right section, or the
coverage tools won't work.
llvm-svn: 228794
We don't emit any coverage mapping for uncovered functions that come
from system headers, but we were creating a GlobalVariable with each
of their names. This is wasteful since the linker will need to dead
strip the unused symbols, and it can lead to issues when merging
coverage with others TUs that do have coverage for those functions.
