This tries to make use of evaluateAsRelocatable in AArch64AsmParser::classifySymbolRef to parse more complex expressions as relocatable operands. It is hopefully better than the existing code which only handles Symbol +- Constant. This allows us to parse more complex adr/adrp, mov, ldr/str and add operands. It also loosens the requirements on parsing addends in ld/st and mov's and adds a number of tests. Differential Revision: https://reviews.llvm.org/D51792 llvm-svn: 342455
