This patch implements the demangling functionality as described in the Vector Function ABI. This patch will be used to implement the SearchVectorFunctionSystem (SVFS) as described in the RFC: http://lists.llvm.org/pipermail/llvm-dev/2019-June/133484.html A fuzzer is added to test the demangling utility. Patch by Sumedh Arani <sumedh.arani@arm.com> Differential revision: https://reviews.llvm.org/D66024 llvm-svn: 372343
