cmd/compile: fix SIMD type parameter instantiation
When a SIMD type is used to instantiate a type parameter, the SIMD's
underlying type is its shape. This shape type must be marked as a SIMD
type, otherwise, the backend will confuse and does not know how to put
this SIMD type to proper registers.
Fixing this by marking a type as SIMD type if its underlying is already
a SIMD one.
Fixes #77444
