Reimplement the intrinsic verifier to use the same table as Intrinsic::getDefinition,
making it stronger and more sane. Delete the code from tblgen that produced the old code. Besides being a path forward in intrinsic sanity, this also eliminates a bunch of machine generated code that was compiled into Function.o git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157545 91177308-0d34-0410-b5e6-96231b3b80d8
