Xinliang David Li f920e4b123 [PGO] Test case update
Temporarily relax check in test to avoid 
  breakage for format change in LLVM side. Once that is
  done, the test case will be retightened.

Rong Xu 9837ef56b4 [PGO] cc1 option name change for profile instrumentation
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.

Xinliang David Li 8608513b69 [PGO] Shorten profile symbol prefixes
(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.

Xinliang David Li aab1fd16bc [PGO] Stop using invalid char in instr variable names.

Xinliang David Li 871daea550 [PGO] Stop using invalid char in instr variable names.
(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.

Justin Bogner 60d852ba5b InstrProf: Fix a shadowing error that would break length of profile names
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.

Justin Bogner 2368c82de0 InstrProf: Add a test for PR22531
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.

Justin Bogner 00270df517 InstrProf: Avoid creating profile names for symbols in system headers
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.
