[compiler-rt] dd1ea9d - Reland: [Coverage] Revise format to reduce binary size

[Jeremy Morse via llvm-commits]

Hi Vedant,

We're seeing the following test fail with this commit:

  compiler-rt/test/profile/instrprof-merging.cpp

Which has also knackered one of the sanitizer buildbots ("test
standalone compiler-rt"):

  http://lab.llvm.org:8011/builders/sanitizer-x86_64-linux/builds/25925

Note that build 25923 fails for different reasons, and build 25924
fails too because it contains the previous land of D69471.
