Russ Cox 0256ba99a8 [dev.regabi] cmd/compile: split up typecheck1 [generated] 
typecheck1 is the largest non-machine-generated function in the compiler.
weighing in at 1,747 lines. Since we are destroying the git blame history
anyway, now is a good time to split each different case into its own function,
making future work on this function more manageable.
