  [llvm-cov] Add inline exclusion marker support for coverage reporting

Add --exclude-line-regex, --exclude-region-start-regex, and
--exclude-region-stop-regex options to llvm-cov. These allow excluding
lines from coverage totals based on inline source comments.

Defaults: LCOV_EXCL_LINE (single line), LCOV_EXCL_START/LCOV_EXCL_STOP
(region). This brings parity with lcov/gcov's exclusion markers and
kcov's --exclude-line regex support.

The implementation scans source files for markers when loaded, builds a
per-file set of excluded line numbers, and subtracts them from the line
coverage totals in prepareFileReports(). Excluded lines are also hidden
from the "show" output (no count column, no red highlighting).
