Robert Griesemer 539aa05a64 cmd/compile: towards simpler and faster lexing: always use getr ... Always reading runes (rather than bytes) has negligible overhead (a simple if at the moment - it can be eliminated eventually) but simplifies the lexer logic and opens up the door for speedups. In the process remove many int conversions that are now not needed anymore. Also, because identifiers are now more easily recognized, remove talph label and move identifier lexing "in place". Also, instead of accepting all chars < 0x80 and then check for "frogs", only permit valid characters in the first place. Removes an extra call for common simple tokens and leads to simpler logic. `time go build -a net/http` (best of 5 runs) seems 1% faster. Assuming this is in the noise, there is no noticeable performance degradation with this change.
