parser: Propagate type hint value

Type hint value was not propagated correctly to LiteralPattern in ast.
This was defaulted to CORETYPE_STR instead, which introduced several
bugs with systems that did require any ast collection.

gcc/rust/ChangeLog:

	* ast/rust-pattern.h: Change constructor to accept new parameter
	instead of defaulting on string type.
	* parse/rust-parse-impl.h (Parser::parse_literal_or_range_pattern):
	Propagate type hint.
	(Parser::parse_pattern_no_alt): Likewise.
