3125af2b6b [compiler-rt] [test] [profile] Avoid issues with an implicit .exe suffix
Mingw toolchains implicitly add an .exe suffix if the output linked
file doesn't have a suffix. In many cases the extra suffix doesn't
cause any issues, but in some tests, this discrepancy between expected
output file name and actual output file does affect the tests.

In one test, a rm command fails to remove the executable since it
doesn't have the expected name. By failing to remove the executable, the
later llvm-profdata command tries to read the executable as if it was
a profile data file.

In another test, when the Python executor executes commands, it can
resolve executable names without the extra .exe suffix for absolute
paths (when most binaries are executed as e.g. "%t/foo"), but it fails
to resolve the executables for relative paths such as "./foo". Making
the paths absolute by using %t here shouldn't affect what the test tries
to validate.

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.

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.

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.
