resolve: Handle multiple bindings to the same identifier
https://github.com/rust-lang/rust/blob/master/compiler/rustc_resolve/src/late.rs#L3168
This commit follows rustc's implementation of handling multiple bindings
to the same identifier in parameters.
gcc/rust/ChangeLog:
* resolve/rust-ast-resolve-expr.cc (ResolveExpr::visit) :declare and
pass bindings to PatternDeclaration::go.
(ResolveExpr::resolve_closure_param): Likewise.
* resolve/rust-ast-resolve-expr.h: Likewise.
* resolve/rust-ast-resolve-item.cc (ResolveTraitItems::visit): Likewise.
(ResolveItem::visit): Likewise.
* resolve/rust-ast-resolve-pattern.cc (PatternDeclaration::go): Likewise.
(PatternDeclaration::visit): check for previous identifier bindings
before inserting the new one.
* resolve/rust-ast-resolve-pattern.h (enum PatternBoundCtx): New enum.
* resolve/rust-ast-resolve-stmt.h: pass bindings to PatterDeclaration::go.
gcc/testsuite/ChangeLog:
* rust/compile/multiple_bindings1.rs: New test.
