Support passing and returning values of single-element vector
types (i.e. <1 x i128> and <1 x fp128>).
Now that i128 is a legal type, supporting these types can be
done simply by providing a getRegisterTypeForCallingConv
implementation that handles them.
Fixes https://github.com/llvm/llvm-project/issues/61291
This adds support for the new 32-bit vector float instructions of z14.
This includes:
- Enabling the instructions for the assembler/disassembler.
- CodeGen for the instructions, including new LLVM intrinsics.
- Scheduler description support for the instructions.
- Update to the vector cost function calculations.
In general, CodeGen support for the new v4f32 instructions closely
matches support for the existing v2f64 instructions.
