gccrs: Implement quick-check for Unicode

gcc/rust/ChangeLog:

	* rust-system.h: Add <algorithm>.
	* util/make-rust-unicode.py: Output NFC_Quick_Check table.
	* util/rust-codepoint.h (struct Codepoint): Add is_supplementary
	method.
	* util/rust-unicode-data.h: Generated.
	* util/rust-unicode.cc (lookup_cc): Remove namespace.
	(is_alphabetic): Likewise.
	(nfc_quick_check): New function.
	(nfc_normalize): Use nfc_quick_check.
	(is_nfc_qc_maybe): New function.
	(is_nfc_qc_no): New function.
	(rust_nfc_qc_test): New test.
	* util/rust-unicode.h (is_nfc_qc_no): New function.
	(is_nfc_qc_maybe): New function.
	(enum class): New enum class.
	(nfc_quick_check): New function.
	(rust_nfc_qc_test): New test.
