Dan Scales 099b819085 cmd/compile: fix CheckSize() calculation for -G=3 and stencils
Because the Align/Width of pointer types are always set when created,
CalcSize() never descends past a pointer. Therefore, we need to do
CheckSize() at every level when creating type. We need to do this for
types creates by types2-to-types1 conversion and also by type
substitution (mostly for stenciling). We also need to do
Defer/ResumeCheckSize() at the top level in each of these cases to deal
with potentially recursive types.

These changes fix issue #47929 and also allow us to remove the
special-case CheckSize() call that causes the problem for issue #47901.

Fixes #47901
Fixes #47929
