cmd/compile/internal/gc: recursive-descent parser This is a translation of the yacc-based parser with adjustements to make the grammar work for a recursive-descent parser followed by cleanups and simplifications. The yacc actions were mostly literally copied for correctness with better temporary names. A few of the syntax tests were adjusted for slightly different error messages (it is very difficult to match the yacc-based error messages in all cases, and sometimes the new parser could produce better errors). The new parser is enabled by default. To switch back to the yacc-based parser, set -oldparser. To hardwire the switch back, uncomment "oldparser = 1" in lex.go. - passes all.bash - ~18% reduced parse time per file on average for make.bash - ~3% reduced compile time for building cmd/compile Change-Id: Icb5651bb9d8b9f66261762d2c94a03793050d4ce Reviewed-on: https://go-review.googlesource.com/16665 Run-TryBot: Robert Griesemer <gri@golang.org> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by: Russ Cox <rsc@golang.org> 2015-11-04 10:21:49 -07:00			`else { } // ERROR "unexpected semicolon or newline before .?else.?\|unexpected else"`
