[Profile] Allow online merging with debug info correlation.
When using debug info correlation, value profiling needs to be switched off.
So, we are only merging counter sections. In that case the existance of data
section is just used to provide an extra check in case of corrupted profile.
This patch performs counter merging by iterating the counter section by counter
size and add them together.

[InstrProf] Report error when merging temporal profiles
Temporal profiles do not support profile merging at runtime. The reason
is that each function can only store one timestamp and the
`llmv-profdata` tool is responsible for sampling traces during the merge
command. Report an error in `__llvm_profile_merge_from_buffer()` if
merging a temporal profile.
The added test also checks that lightweight profiles throw an error,
although this may be fixed in https://reviews.llvm.org/D157632
