Change keyword set to a map
Some part of the code requires the token id behind a given keyword, a map
keep the "set" aspect whilst providing this additional feature.
gcc/rust/ChangeLog:
* lex/rust-lex.cc (RS_TOKEN): Remove local map.
(RS_TOKEN_KEYWORD): Likewise.
(Lexer::classify_keyword): Change call to utils.
* util/rust-keyword-values.cc (get_keywords): Add init function.
(RS_TOKEN_KEYWORD): Call to X macro.
* util/rust-keyword-values.h: Change from set to a map.
