Manman Ren e73ae9a142 Reland compiler-rt support for order file instrumentation.
r355343 was landed and was reverted in r355363 due to build breakage.
This patch adds Linux/Windows support on top of r355343.

In this patch, Darwin should be working with testing case. Linux should be working,
I will enable the testing case in a follwup diff. Windows/Other should be building.
Correct implementation for Other platforms will be added.

Thanks David for reviewing the original diff, helping me with issues on Linux, and
giving suggestions for adding support for Other platforms.

Ana Pazos bbb8129b2c Set hidden attribute on lprofMergeValueProfData
Summary:
The changes in https://reviews.llvm.org/D44847 cause load time failure
due to lprofMergeValueProfData in Android libs enabled with profile generation:

"dlopen failed: cannot locate symbol "lprofMergeValueProfData" referenced by..."

Marking lprofMergeValueProfData as hidden so the correct in-module definition
 is picked by the linker.

Reid Kleckner 17e2521724 [InstrProf] Port test suite to Windows
Summary:
Before this change, check-profile would run, but all tests would be
marked unsupported on Windows. This is the new status of 'check-profile'
after this change:

Testing Time: 6.66s
  Expected Passes    : 29
  Expected Failures  : 5
  Unsupported Tests  : 39

I moved many tests that exercise posix-y features like dlopen and DSOs
into the Posix subdirectory, and ran the tests on Linux to validate my
changes.

These are the remaining tests that I handled on a case by case basis:
- instrprof-path.c
  Passes, Fixed some path portability issues
- instrprof-gcov-exceptions.test
  Passes, the FileCheck actually succeeds on Windows, so I RUNX'd it
- instrprof-icall-promo.test
  XFAILed, probably due to C++ ABI differences in vtables
- instrprof-merge-match.test
- instrprof-merge.c
- instrprof-merging.cpp
  XFAILed, These seem like real bugs that need fixing
- instrprof-version-mismatch.c
  XFAILed, Overriding the weak version symbol doesn't work
- instrprof-without-libc.c
  UNSUPPORTED, test needs an executable symbol table, Windows has none

Vedant Kumar 727d89526e [gcov] Fix branch counters with switch statements (fix PR38821)
Right now, the counters are added in regards of the number of successors
for a given BasicBlock: it's good when we've only 1 or 2 successors (at
least with BranchInstr). But in the case of a switch statement, the
BasicBlock after switch has several predecessors and we need know from
which BB we're coming from.

So the idea is to revert what we're doing: add a PHINode in each block
which will select the counter according to the incoming BB.  They're
several pros for doing that:

- we fix the "switch" bug
- we remove the function call to "__llvm_gcov_indirect_counter_increment"
  and the lookup table stuff
- we replace by PHINodes, so the optimizer will probably makes a better
  job.

Summary:
This will make the behavior of __gcov_flush match the GCC behavior.

I would like to rename __gcov_flush to __llvm_gcov_flush (in case of programs linking to libraries built with different compilers), but I guess we can't for compatibility reasons.
