Before this patch, when an unknown symbol type is used in IFS stub, it
will be treated as a NO_TYPE and parsed without error. This patch makes
llvm-ifs throw an error when this scenario happens.
This reverts commit fd4808887ee47f3ec8a030e9211169ef4fb094c3.
This patch causes gcc to issue a lot of warnings like:
warning: base class ‘class llvm::MCParsedAsmOperand’ should be
explicitly initialized in the copy constructor [-Wextra]
This diff changes llvm-ifs to use unified IFS file format
and perform other renaming changes in preparation for the
merging between elfabi/ifs.
