[profile] Create only prof header when no counters
When we use selective instrumentation and instrument a file
that is not in the selected files list provided via -fprofile-list,
we generate an empty raw profile. This leads to empty_raw_profile
error when we try to read that profile. This patch fixes the issue by
generating a raw profile that contains only a profile header when
there are no counters and profile data.
A small reproducer for the above issue:
echo "src:other.cc" > code.list
clang++ -O2 -fprofile-instr-generate -fcoverage-mapping
-fprofile-list=code.list code.cc -o code
./code
llvm-profdata show default.profraw
