gccrs: Handle IfLetExprConseqElse in DefaultResolver

This relies on the DefaultASTVisitor visitor for IfLetExprConseqElse
performing a virtual call of the visitor for IfLetExpr, which doesn't
hold when DefaultASTVisitor is generated by the X-macro-DSL-system I
have in another patch.

gcc/rust/ChangeLog:

	* resolve/rust-default-resolver.cc (DefaultResolver::visit): Add
	visitor for IfLetExprConseqElse.
	* resolve/rust-default-resolver.h (DefaultResolver::visit):
	Likewise.
