[TableGen][RISCV] Add InstAliases with zero_reg to cover unmasked vnot.v, vncvt.x.x.w, vneg.v, etc.
The mask being NoRegister prevented the existing aliases from matching
since NoRegister isn't in t
[TableGen][RISCV] Add InstAliases with zero_reg to cover unmasked vnot.v, vncvt.x.x.w, vneg.v, etc.
The mask being NoRegister prevented the existing aliases from matching
since NoRegister isn't in the VMV0 register class.
To workaround this I've added new aliases that look for zero_reg.
I had to motify tablegen to generate matching code for zero_reg.
And as a consequence, I had to change the EmitPriority for an ARM
alias that used zero_reg that started printing.

[RISCV] Add +experimental-zvfh extension to cover half types in vectors.
Currently we allow half types in vectors if the scalar Zfh extension
is enabled. This behavior is not inline with the vector spec. For f32
and f64 types, the Zve32f, Zve64f, Zve64d, and V explicitly control
the availablity of floating point types in vectors.
In order to make our compiler compliant, we either need to remove all support
for half in vectors or we need an extension to control it.
Draft spec here https://github.com/riscv/riscv-v-spec/pull/780

[RISCV] Add inline expansion for vector fround.
This avoids a crash for scalable vectors and or scalarization for
fixed vectors.
The algorithm is different enough that I don't think it makes sense
[RISCV] Add inline expansion for vector fround.
This avoids a crash for scalable vectors and or scalarization for
fixed vectors.
The algorithm is different enough that I don't think it makes sense
to merge with ceil/floor/trunc. Algorithm is adapted from gcc's X86
SSE2 output.
