  [CIR][NEON] Add lowering for `vnegd_s64` and `vnegh_f16` (#180597)

Add CIR lowering support for the non-overloaded NEON intrinsics
`vnegd_s64` and `vnegh_f16`.

The associated tests are shared with the existing default codegen tests:
  * `neon-intrinsics.c` → `neon/intrinsics.c`
  * `v8.2a-fp16-intrinsics.c` → `neon/fullfp16.c`

A new test file,
  * `clang/test/CodeGen/AArch64/neon/fullfp16.c`

is introduced and is intended to eventually replace:
  * `clang/test/CodeGen/AArch64/v8.2a-fp16-intrinsics.c`

Since both intrinsics are non-overloaded, the CIR and default codegen
handling is moved to the appropriate switch statements. The previous
placement was incorrect.

This change also includes minor refactoring in `CIRGenBuilder.h` to
better group related hooks.
