This makes __llvm_profile_set_filename() work across dylib boundaries on
Darwin.
This functionality was originally meant to work on all platforms, but
was moved to a Linux-only directory with r272404. The root cause of the
test failure on Darwin was that lprofCurFilename was not marked weak.
Each dylib maintained its own copy of the variable due to the two-level
namespace.
Tested with check-profile (on Darwin). I don't expect this to regress
other platforms.

Profile-aarch64 :: Linux/comdat_rename.test
Profile-aarch64 :: Linux/extern_template.test
Profile-aarch64 :: Linux/instrprof-comdat.test
Profile-aarch64 :: Linux/instrprof-cs.c
The issue is that the created (aarch64) binaries were attempting to run natively
instead of running through %run, which guarantees running in the proper
environment if the compilation was configured correctly.

Another CFG optimisation patch (280364) has broken bad profile tests, and this
is a similar attempt to fix the test without changing the semantics.

Commit r280364 has introduced some call-graph optmisations making a profiler
test "fail" due to not expecting the compiler to be "smart", and fold constants
across functions. This commit works around the issue, leaving the origial
semantics intact.

The API is intended to be used by user to do fine
grained (per-region) control of profile dumping.

Summary:
This patch is a refactoring of the way cmake 'targets' are grouped.
It won't affect non-UI cmake-generators.
Clang/LLVM are using a structured way to group targets which ease
navigation through Visual Studio UI. The Compiler-RT projects
differ from the way Clang/LLVM are grouping targets.
This patch doesn't contain behavior changes.

Test that __llvm_profile_set_filename invoked in
main program is 'visible' to shared lib (overriding
shared libary's profile path set on command line)

(Part-1 merging API is in profile runtime)
This patch implements a portable file opening API
with exclusive access for the process. In-process
profile merge requires profile file update to be
atomic/fully sychronized.

Make sure inline virtual function's address is properly recorded and
dumped in raw profile so that value profiling does not loss tracking.
(Second part of the test will be enabled after the lowering bug is fixed
in LLVM)

With this change, dynamic memory allocation is only used
for testing purpose. This change is one of the many steps to
make instrument profiler dynamic allocation free.
