Subject: [PATCH 1/2] [WIP][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 `__fpm8` 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 fpm8_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.
