In CL 326211 a change was made to switch "go.map.zero" symbols from
non-pkg DUPOK symbols to hashed symbols. The intent of this change was
ensure that in cases where there are multiple competing go.map.zero
symbols feeding into a link, the largest map.zero symbol is selected.
The change was buggy, however, and resulted in duplicate symbols in
the final binary (see bug cited below for details). This duplication
was relatively benign for linux/ELF, but causes duplicate definition
errors on Windows.
This patch switches "go.map.zero" symbols back from hashed symbols to
non-pkg DUPOK symbols, and updates the relevant code in the loader to
ensure that we do the right thing when there are multiple competing
DUPOK symbols with different sizes.
Fixes#47185.

Distinguish the gcshape of all top-level instantiated type from normal
concrete types, even if they have the exact same underlying "shape",
because in a function instantiation, any method call on this type arg
will be a generic method call (requiring a dictionary), rather than a
direct method call on the underlying type (no dictionary).
So, we add the instshape prefix to the gcshape name for instantiated
types, and we make it a defined type with that name.

When instantiating a generic type or function with multiple type
arguments, we need to represent an index expression with multiple
indexes in the AST. Previous to this CL this was done with a new
ast.ListExpr node, which allowed packing multiple expressions into a
single ast.Expr. This compositional pattern can be both inefficient and
cumbersome to work with, and introduces a new node type that only exists
to augment the meaning of an existing node type.
By comparison, other specializations of syntax are given distinct nodes
in go/ast, for example variations of switch or for statements, so the
use of ListExpr was also (arguably) inconsistent.
This CL removes ListExpr, and instead adds a MultiIndexExpr node, which
is exactly like IndexExpr but allows for multiple index arguments. This
requires special handling for this new node type, but a new wrapper in
the typeparams helper package largely mitigates this special handling.

The compiler is relying on Sym.Def field to lookup symbol package in
DotImportRefs map. But the Sym.Def field is clear whenever the compiler
finish processing a file. If the dot import happen in file A, then the
redeclaration happen in file B, then the symbol lookup in file B will
see a nil Sym.Def, that cause the compiler crashes.
To fix this, we can interate over DotImportRefs and check for matching
symbol name and return the corresponding package. Though this operation
can be slow, but it only happens in invalid program, when printing error
message, so it's not worth to optimize it further.
