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.

Fangrui Song c5b94ea265 [profile] Support merge pool size >= 10
The executable acquires an advisory record lock (`fcntl(fd, F_SETLKW, *)`) on a profile file.
Merge pool size >= 10 may be beneficial when the concurrency is large.

Also fix a small problem about snprintf. It can cause the filename to be truncated after %m.

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 cc0d7eeb6d profile: Avoid name collisions between instrumentation and runtime
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.
