[CLANG][AArch64] Add the modal 8 bit floating-point scalar type
ARM ACLE PR#323[1] adds new modal types for 8-bit floating point intrinsic. From the PR#323: ``` ACLE defines the `__mfp8` type, which can be used for the E5M2 and E4M3 8-bit floating-point formats. It is a storage and interchange only type with no arithmetic operations other than intrinsic calls. ```` The type should be an opaque type and its format in undefined in Clang. Only defined in the backend by a status/format register, for AArch64 the FPMR. This patch is an attempt to the add the MFloat8_t scalar type. It has a parser and codegen for the new scalar type. The patch it is lowering to and 8bit unsigned as it has no format. But maybe we should add another opaque type. [1] ARM-software/acle#323
