This patch adds support for expanding "%h" out to the machine hostname
in the LLVM_PROFILE_FILE environment variable.

The original submittion triggered a BFD linker bug (2.24) on Aarch64 only. Before
the build bot is upgraded to more recent linker, restrict the test to be
executed only with gold linker.

(second try with more strict config check)
Currently, only gc-sections related tests are added. Gold
linker currently is required due to PR19161 of bfd linker.

IR level instrumentation needs to override version with variant bits.
No change for FE instrumentation is needed. Test case is added to
detect version mismatch.

Extract the buffered filer writer code used by value profile
writer and turn it into common/sharable buffered fileIO
interfaces. Added a test case for the buffered file writer and
rewrite the VP dumping using the new APIs.
llvm-svn: 256604
The profile reader no longer depends on this field to be updated and point
to owning func's vp data. The VP data also no longer needs to be allocated
in a contiguous memory space.

Add a test case to cover profile dumping of functions with no
value sites, functions with value sites but no dynamic VP data,
and functions with runtime VP data.
llvm-svn: 255327
Value profile runtime depends on libc which breaks
buffer API implemenation with current file organization.
Test case is also updated to check more symbols.

and -no-integrated-as for source with static function.
The compiler generates assembly names containing \" in the
.s dump causing gnu assembler to complain. That issue will be
investigated separately.

With the latest refactoring and code sharing patches landed,
it is possible to unify the value profile implementation between
raw and indexed profile. This is part in prfofile runtime.

- This is to handle a corner case where profile lib is linked
in but non of the modules are instrumented (On linux, since
we avoided the overhead to emit runtime hook use functions so
this is the side effect of that size optimization).
- Added a profile runtime test case to cover all scenarios of
shared library builds.

When the file is initialized, this patch checks whether the path
specifies a directory. If so, it creates the directory tree before
truncating the file.
Use default.profdata instead of pgo-data for default indexed profile name.

Fix a couple of new tests that were reverted because they were causing
intermittent test failures since they were writing the same default
"default.profraw" file. Fixed by creating a unique directory and
running tests in that directory.
Patch by Teresa Johnson. Thanks!

This partially reverts commit r236056, as the two tests were using the same
names and, when executed in parallel, were having intermittent failures.

Summary:
I don't know anything about profiling but it seems to work out of the
box on PowerPC64. At least "make check-profile" works.
A few tests needed tweaking because PowerPC64 IR declares main with
"define signext i32 @main" instead of just "define i32 @main".
This also fixes the asan asan_and_llvm_coverage_test test, which
compiles with -coverage so requires that a profiling version of
libclang_rt has been built.

ASAN, UBSAN and profile tests that don't work with arm-linux-gnueabi and
android also don't work on armv7l-linux-gnueabihf. Some of the tests have
known causes, others not yet. In order to get a green bot, I'm disabling
those tests for now and will investigate when the priority rises.

FreeBSD does not have libdl, so set it via lit.cfg instead of the test
input, as with asan. Also remove it from Darwin test runs - it's not
necessary, but harmless there.
Add FreeBSD to the list of hosts to test.

The naming scheme we're using for counters in profile data shares a
prefix with some fixed names we use for the runtime, notably
__llvm_profile_data_begin and _end. Embarrassingly, this means a
function called begin() can't be instrumented.
This modifies the runtime names so as not to collide with the
instrumentation.
