if falseReg == embMaskOp2Reg, we simply generate:
```
sel z16.s, p7, z9.s, z10.s
mla z16.s, p7/m, z10.s, z11.s
```
Here `z10` holds `falseReg` and `embMaskOp2Reg`.

* handle case for FMA where falseReg == embMaskOp1Reg
* workaround because predicateRegister/vectorRegister are same
* When intrinsic is wrapped in ConditionalSelect, make sure to check its LOW_PREDICATE flag
* Mark AddAcross with HW_Flag_LowMaskedOperation
* double check if ConditionalSelect's op2 is hwintrinsic
* Mark Max with HW_Flag_LowMaskedOperation
* Mark MaxAcross with HW_Flag_LowMaskedOperation
* Mark MinNumber/MaxNumber/MinNumberAcross/MaxNumberAcross with HW_Flag_LowMaskedOperation
* Mark Min/MinAcross with HW_Flag_LowMaskedOperation
* fix the workaround for predicate vs. vector register
* fix the predicate mask preference
* Introduce INS_SCALABLE_OPTS_PREDICATE_MERGE_MOV
* jit format
* revert change to csproj
* remove assert that can not happen for FMA
if falseReg == embMaskOp2Reg, we simply generate:
```
sel z16.s, p7, z9.s, z10.s
mla z16.s, p7/m, z10.s, z11.s

* revert a condition added for workaround of predicate == vector register
* remove the extra comment

falseReg == embMaskOp1Regmovwhen used as alias forselbecause predicateRegister/vectorRegister are sameConditionalSelect, check the intrinsic flag if it needs low register maskHW_Flag_LowMaskedOperationThere are still some functional failures with JitStress/JitStressRegs, but wanted to send this out.
