[llvm] r229841 - Reverting r229831 due to multiple ARM/PPC/MIPS build-bot failures.

[Daniel Sanders]

Hi,

I can't reproduce it from a cmake+ninja build with 'CMAKE_BUILD_TYPE=' build but I can from a 'CMAKE_BUILD_TYPE=Release' build.

When 'CMAKE_BUILD_TYPE=', the command to build lib/Target/X86/MCTargetDesc/CMakeFiles/LLVMX86Desc.dir/X86MCTargetDesc.cpp.o takes around 50s and ~500MB RAM.
When 'CMAKE_BUILD_TYPE=Release', it takes ~30mins and the memory usage very slowly creeps upwards until the process is killed at 1GB.
