gccrs: nr1.0: Remove support in pattern checker

gcc/rust/ChangeLog:

	* checks/errors/rust-hir-pattern-analysis.cc: Remove inclusion
	of "options.h".
	(PatternChecker::PatternChecker): Change initialization of
	resolver reference.
	(PatternChecker::visit): Assume name resolution 2.0 is enabled.
	* checks/errors/rust-hir-pattern-analysis.h: Include nr2.0
	header instead of nr1.0 header.
	(PatternChecker::resolver): Change type to nr2.0 resolver.
