[FastISel][AArch64] Use the correct register class to make the MI verifier happy. This is mostly achieved by providing the correct register class manually, because getRegClassFor always returns the GPR*AllRegClass for MVT::i32 and MVT::i64. Also cleanup the code to use the FastEmitInst_* method whenever possible. This makes sure that the operands' register class is properly constrained. For all the remaining cases this adds the missing constrainOperandRegClass calls for each operand. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@216225 91177308-0d34-0410-b5e6-96231b3b80d8

[FastISel][AArch64] Add support for frameaddress intrinsic. This commit implements the frameaddress intrinsic for the AArch64 architecture in FastISel. There were two test cases that pretty much tested the same, so I combined them to a single test case.
