Introduce SingleByteCoverage tests (w/yaml2obj) (#113114)
Restructure some tests to split into `%.test` and Inputs/%.c*`.
Add test actions with `yaml2obj` for single byte coverage. `FileCheck`
lines are:
- Relax to accept both counter values and single values `1`. A few line
counting are greater than `1` due to `llvm-profdata merge`. They will be
fixed by #110972.
- Suppress matching with `--check-prefixes=CHECK,BRCOV`, since the
current implementation of single byte doesn't emit any branch coverages.
They will be integrated to `CHECK` finally.
- Some tests are not unified but use dedicated `CHECK` lines for single
byte, since old format is different (esp. "partial fold"). They will be
unified when `Inputs` will be regenerated.
Introduce llvm/test/tools/llvm-cov/Inputs/yaml.makefile for convenience.
`%-single.yaml` and `%-single.proftext` are generated by it. It could be
used to regenerate other files.

[InstrProf] Single byte counters in coverage (#75425)
This patch inserts 1-byte counters instead of an 8-byte counters into
llvm profiles for source-based code coverage. The origial idea was
proposed as block-cov for PGO, and this patch repurposes that idea for
coverage: https://groups.google.com/g/llvm-dev/c/r03Z6JoN7d4
The current 8-byte counters mechanism add counters to minimal regions,
and infer the counters in the remaining regions via adding or
subtracting counters. For example, it infers the counter in the if.else
region by subtracting the counters between if.entry and if.then regions
in an if statement. Whenever there is a control-flow merge, it adds the
counters from all the incoming regions. However, we are not going to be
able to infer counters by subtracting two execution counts when using
single-byte counters. Therefore, this patch conservatively inserts
additional counters for the cases where we need to add or subtract
counters.
