This patch enables the the Cortex-A55 model, which we can apply after we're happy with the schedmodel improvements that we still need to do.

The added LLVM-MCA test is based on all the basic A64 instruction taken from this disassembler test:

  llvm/test/MC/Disassembler/AArch64/basic-a64-instructions.txt

In a follow up, we can complete and fill in other instructions.
