Arthur Eubanks 10f2a0d662 Use uint64_t for branch weights instead of uint32_t
CallInst::updateProfWeight() creates branch_weights with i64 instead of i32.
To be more consistent everywhere and remove lots of casts from uint64_t
to uint32_t, use i64 for branch_weights.

Duncan P. N. Exon Smith 4a7fddca0d Update lib/profile tests for metadata assembly change
Running the upgrade script from PR21532.  Hopefully this will unstick
compiler-rt bots [1] after r224257.

Justin Bogner aa5bb91f5a profile: Robustify instrprof tests
Change these tests not to rely on the exact metadata numbers the
profile data gets.

Jay Foad 8e586617c4 InstrProf: support PowerPC64
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.

Duncan P. N. Exon Smith 238137294f InstrProf: Test the functions in the runtime
Check that the profile runtime works as expected.  This tests the
functions that are meant to be available to advanced users.

In particular, check that the `atexit()` hook can be disabled by
defining a custom `__llvm_profile_runtime` variable, that the libc
dependencies are optional, and that the various functions for writing
out files work for basic cases.
