[AArch64][GlobalISel] Mark G_INTRINSIC_ROUND as a pre-isel floating point opcode
Add G_INTRINSIC_ROUND to isPreISelGenericFloatingPointOpcode to ensure that its input and output are assigned the correct register bank. Add a regbankselect test to verify that we get what we expect here. llvm-svn: 359044
