gccrs: Implement quick-check for Unicode

gcc/rust/ChangeLog: * rust-lang.cc (run_rust_tests): Add test. * 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 (binary_search_sorted_array): Removed. (lookup_cc): Remove namespace. (is_alphabetic): Use std::binary_search (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. Signed-off-by: Raiki Tamura <[email protected]>
