[RISCV] Add 32 bit GPR sub-register for Zfinx. (#108336)
This patches adds a 32 bit register class for use with Zfinx instructions. This makes them more similar to F instructions and allows us to only spill 32 bits.
I've added CodeGenOnly instructions for load/store using GPRF32 as that gave better results than insert_subreg/extract_subreg.
Function arguments use this new GPRF32 register class for f32 arguments with Zfinx. Eliminating the need to use RISCVISD::FMV* nodes.
This is similar to #107446 which adds a 16 bit register class.

[RISCV] Omit "@plt" in assembly output "call foo@plt" (#72467)
R_RISCV_CALL/R_RISCV_CALL_PLT distinction is not necessary and
R_RISCV_CALL has been deprecated. Since https://reviews.llvm.org/D132530
[RISCV] Omit "@plt" in assembly output "call foo@plt" (#72467)
R_RISCV_CALL/R_RISCV_CALL_PLT distinction is not necessary and
R_RISCV_CALL has been deprecated. Since https://reviews.llvm.org/D132530
`call foo` assembles to R_RISCV_CALL_PLT. The `@plt` suffix is not
useful and can be removed now (matching AArch64 and PowerPC).
GNU assembler assembles `call foo` to RISCV_CALL_PLT since 2022-09
(70f35d72ef04cd23771875c1661c9975044a749c).
Without this patch, unconditionally changing MO_CALL to MO_PLT could
create `jump .L1@plt, a0`, which is invalid in LLVM integrated assembler
and GNU assembler.

[RISCV] Add rv32i/rv64i command lines to some floating point tests. NFC
This improves our coverage of soft float libcalls lowering.
Remove most of the test cases from rv64i-single-softfloat.ll. They
were duplicated in the test files that now test softflow. Only
a couple test cases for constrained FP remain. Those should be
removed when we start supporting constrained FP.
This is follow up from D113528.
