[TTI][RISCV] Implement cost of some intrinsics with LMUL (#117874)

Intrinsics include:
sadd_sat/ssub_sat/uadd_sat/usub_sat/fabs/fsqrt/cttz/ctlz/ctpop

[RISCV][CostModel] add cost for cttz/ctlz under the non-zvbb (#117515)

[RISCV][CostModel] cost of vector cttz/ctlz under ZVBB (#115800)

[Test] Rename the test function name suffix. NFC (#114504)

[RISCV] Remove -riscv-v-vector-bits-min from cost model tests. NFC

It looks like they were added to prevent fixed length vectors from
being expanded, but that's no longer the case today:

[RISCV] Remove experimental from Vector Crypto extensions (#74213)

The RISC-V vector crypto extensions have been ratified. This patch
updates the Clang and LLVM support for these extensions to be
non-experimental, while leaving the C intrinsics as experimental since
the C intrinsics are not yet standardized.

CostModel/RISCV: tweak cost of vector ctpop under ZVBB (#67020)

Under RISCV experimental-zvbb, vector variants of llvm.ctpop lower to a
single instruction: vcpop. The cost-model does not check for the ZVBB
extension, and always associates a high cost to vector variants of
llvm.ctpop. Fix this defect.

CostModel/RISCV: tweak test for ctpop, with/without ZVBB (#67013)

Vector ctpop only exists under ZVBB, but ZVBB is unaccounted for in the
cost-model of ctpop. Document this defect with an additional RUN line in
the test for ctpop, showing identical costs with/without ZVBB. A
follow-up patch could fix this defect.

[RISCV][CostModel] Add getCFInstrCost RISC-V implementation (#65599)

This patch implements getCFInstrCost TTI hook that mostly affects
LoopVectorizer decisions. It sets zero cost for PHI nodes and zero
throughput cost for branches (assuming that branches are likely to
be predicted). The implementation is similar to X86/AArch64/PowerPC
targets and reduces loop cost by excluding induction PHIs/loop latch
branches, which in turn leads to selecting smaller vectorization
factor.
