D34393 added MCCodePadder as an infrastructure for padding code with NOP instructions. It lacked tests and was not being worked on since then. Intel has now worked on an assembler patch to mitigate performance loss after applying microcode update for the Jump Conditional Code Erratum. https://www.intel.com/content/www/us/en/support/articles/000055650/processors.html This new patch shares similarity with MCCodePadder, but has a concrete use case in mind and is being actively developed. The infrastructure it introduces can potentially be used for general performance improvement via alignment. Delete the unused MCCodePadder so that people can develop the new feature from a clean state. Reviewed By: jyknight, skan Differential Revision: https://reviews.llvm.org/D71106
