This is a feature that is not understood well enough and may have
subtle repercussions impacting future changes. Disable for Go 1.18.
The actual change is trivial: disable a branch through a flag.
The remaining changes are adjustments to tests.
Fixes#51576.

The next CL will remove the -G flag, effectively hard-coding it to its
current default (-G=3).

Given we have support for field access to type params with a single
structural type, we need to distinguish between methods calls and field
access when we have an OXDOT node on an expression which is a typeparam
(or correspondingly a shape). We were missing checks in getInstInfo,
which figures out the dictionary format, which then caused problems when
we generate the dictionaries. We don't need/want dictionary entries for
field access, only for bound method calls. Added a new function
isBoundMethod() to distinguish OXDOT nodes which are bound calls vs.
field accesses on a shape.
Removed isShapeDeref() - we can't have field access or method call on a
pointer to variable of type param type.
Fixes#50690
