other cleanups
The type substituter (typecheck.Typ()) was temporarily substituting from
shapes back to concrete types, but doesn't need to anymore. So, remove
two shape checks, so the type substituter is now only for substituting
type params again.
Several other cleanups:
- renamed makeGenericName() to makeInstName1(), since that function is
a helper to MakeInstName() and MakeDictName() that definitely makes
instantiated names, not generic names.
- removed the logic in makeInstName1() that adds the ".inst." prefix
for concrete type args. We are only specifying concrete type args (as
opposed to shape args) when we are calling from MakeDictName, and
then we immediately strip of the .inst prefix anyway.
- Added a comment on types.Identical that a shape type is considered
identicall to another type if their underlying types are the same, or
they are both pointers.

Except unsafe.Pointer. It has a different Kind, which makes it trickier.

Still 1-1 with real types, but now with their own names!
Shape types are implicitly convertible to (and convertible from)
the types they represent.

types.Type instead
Confusingly, the set of all methods of an interface is currently set in
Fields field of types.Interface. This is true, even though there is
already an allMethods field (and AllMethods method) of types.Type.
Change so the set of all methods of an interface are stored in
Type.allMethods, and Interface.Fields is removed. Update the comments
for Methods and AllMethods.

Previously, we used a single "untyped number" type for all untyped
numeric constants. This led to vague error messages like "string(1.0)"
reporting that "1 (type untyped number)" can't be converted to string,
even though "string(1)" is valid.
This CL makes cmd/compile more like go/types by utilizing
types.Ideal{int,rune,float,complex} instead of types.Types[TIDEAL],
and keeping n.Type in sync with n.Val().Ctype() during constant
folding.
Thanks to K Heller for looking into this issue, and for the included
test case.
Fixes #21979.

This change does a bulk rename of several identifiers in the compiler.
See #27167 and https://docs.google.com/document/d/19_ExiylD9MRfeAjKIfEsMU1_RGhuxB9sA0b5Zv7byVI/
for context and for discussion of these particular renames.
Commands run to generate this change:
gorename -from '"cmd/compile/internal/gc".OPROC' -to OGO
gorename -from '"cmd/compile/internal/gc".OCOM' -to OBITNOT
gorename -from '"cmd/compile/internal/gc".OMINUS' -to ONEG

Not altered: parameters and local variables (mostly in typecheck.go) named top,
which should probably now be called ctx (and which should probably have a named type).
Also not altered: Field called Top in gc.Func.

gorename -from '"cmd/compile/internal/types".fieldIsddd' -to fieldIsDDD
Not altered: function gc.hasddd, params and local variables called isddd
Also not altered: fmt.go prints nodes using "isddd(%v)".

I then manually found impacted comments using exact string match
and fixed them up by hand. The comment changes were trivial.
Passes toolstash-check.
Fixes #27167. If this experiment is deemed a success,
we will open a new tracking issue for renames to do
at the end of the 1.13 cycles.
