After llvm commit e8e2edd8ca88f8b0a7dba141349b2aa83284f3af

Fix test from 8dd42f, capitalization in test
the following benchmarks slowed down by more than 2%:
- 464.h264ref slowed down by 3% from 10973 to 11249 perf samples
- 464.h264ref:[.] FastFullPelBlockMotionSearch slowed down by 12% from 1446
to 1619 perf samples
Below reproducer instructions can be used to re-build both "first_bad" and
"last_good" cross-toolchains used in this bisection. Naturally, the scripts
will fail when triggerring benchmarking jobs if you don't have access to Linaro
TCWG CI.
For your convenience, we have uploaded tarballs with pre-processed source and
assembly files at:

Configuration:
- Benchmark: SPEC CPU2006
- Toolchain: Clang + Glibc + LLVM Linker
- Version: all components were built from their tip of trunk
- Target: aarch64-linux-gnu
- Compiler flags: -O3
- Hardware: NVidia TX1 4x Cortex-A57
This benchmarking CI is work-in-progress, and we welcome feedback and
suggestions at linaro-toolchain@lists.linaro.org . In our improvement plans is
to add support for SPEC CPU2017 benchmarks and provide "perf report/annotate"
data behind these reports.
THIS IS THE END OF INTERESTING STUFF. BELOW ARE LINKS TO BUILDS, REPRODUCTION
INSTRUCTIONS, AND THE RAW COMMIT.
