[dev.typeparams] cmd/compile:  separate out creating instantiations from creating dictionaries

We often need to create a function/method instantiation, but not a
dictionary, because the call to the instantiation will be using a
sub-dictionary. Also, main dictionaries are only need for concrete,
non-gcshape types, whereas instantiations will be for gcshape types (or
concrete types, for strict stenciling).

Created a helper function getDictOrSubdict() to reduce duplicated code.
Also, moved gfGetGfInfo() call in getDictionarySym() inside conditional
where it is needed, to avoid extra work when dictionary has already been
created.
