Subject: [PATCH] [Coverage][llvm-cov] Correctly export branch coverage in LCOV
 format

Commit 9f2967bcfe2f7d1fc02281f0098306c90c2c10a5 introduced support for
branch coverage including export to the LCOV format.

This commit corrects the LCOV field name for branches from BFH to BRH.
The mistake seems to have slipped in as typo because the correct field
name BRH is used in the comment section at the beginning of the file.
