9a934d5080 [dev.simd] cmd/compile, simd: added methods for "float" GetElem
This also required a "always use operation with least
OverrideBase" filter in choosing the machine instructions.

The order of generated HW operations is slightly
modified because the Float version of GetElem
appears earlier in the sorted operations list,
though it is not chosen to generate the HW Op.

ddb689c7bb [dev.simd] simd, cmd/compile: generated code for Broadcast
Generated by simdgen CL 693599

This turned out to require some additional work in
other places, including filling in missing
methods (use OverwriteBase to get FP versions).

Also includes a test.

38b76bf2a3 [dev.simd] cmd/compile, simd: jump table for imm ops
This CL fixes some errors in prog generation for imm operations, please
see the changes in ssa.go for details.

This CL also implements the jump table for non-const immediate arg. The
current implementation exhaust 0-255, the bound-checked version will be
in the next CL.

8eb5f6020e [dev.simd] cmd/compile, simd: API interface fixes
- Absolute -> Abs
    - ApproximateReciprocal -> Reciprocal
      - Other derived apis also changed.
    - Round -> RoundToEven
      - Other derived apis also changed.
    - Drop DotProdBroadcast
    - Fused(Mul|Add)(Mul|Add)? -> remove the "Fused"
    - MulEvenWiden -> remove 64bit
    - MulLow -> Mul, add unit
    - PairDotProd -> DotProdPairs
      - make AddDotProdPairs machine ops only - peepholes will be in another
        CL at dev.simd.
    - PopCount -> OnesCount
    - Saturated* -> *Saturated
    - Fix (Add|Sub)Saturated uint mappings.
    - UnsignedSignedQuadDotProdAccumulate -> AddDotProdQuadruple
      - The "DotProdQuadruple" instruction does not exist, so no peepholes for
        this.

7ca34599ec [dev.simd] simd, cmd/compile: generated files to add 'blend' and 'blendMasked'
Generated by arch/internal/simdgen CL 693175

These methods are not public because of simdgen-induced name/signature
issues, and because their addition was motivated by the need for
emulation tools.

The specific name signature problems are:

1) one set of instructions has the "Masked" suffix (because of how
that is incorporated into names) and the other set does not (though I
suppose the operation could be renamed).

2) because the AVX2 instruction is bytes-only, to get the signature
right, requires "OverwriteBase" but OverwriteBase also requires
OverwriteClass and "simdgen does not support [OverwriteClass] in
inputs".

3) the default operation order is false, true, but we want this in a
"x.Merged(y, mask)" that pairs with "x.Masked(mask)" where the true
 case is x and the false case is y/zero, but the default ordering for
 VPBLENDVB and VPBLENDMB is false->x and true->y.

4) VPBLENDVB only comes in byte width, which causes problems
for floats.

All this may get fixed in the future, for now it is just an
implementation detail.

7392dfd43e [dev.simd] cmd/compile: generated simd*ops files weren't up to date
I re-ran the generator in arch/internal/simd to
verify a clean move of the intrinsics helpers, and
these changes (which look correct) appeared.

04b1030ae4 [dev.simd] cmd/compile: adapters for simd
This combines several CLs into a single patch of "glue"
for the generated SIMD extensions.

This glue includes GOEXPERIMENT checks that disable
the creation of user-visible "simd" types and
that disable the registration of "simd" intrinsics.

The simd type checks were changed to work for either
package "simd" or "internal/simd" so that moving that
package won't be quite so fragile.

cmd/compile, internal/simd: glue for adding SIMD extensions to Go
cmd/compile: theft of Cherry's sample SIMD compilation
