Fix some grammar inconsistencies for the '..' range notation.
Grammar changes:
* allow 'for _ in 1..i {}' (fixes #20241)
* allow 'for _ in 1.. {}' as infinite loop
* prevent use of range notation in contexts where only operators of high
precedence are expected (fixes #20811)
Parser code cleanup:
* remove RESTRICTION_NO_DOTS
* make AS_PREC const and follow naming convention
* make min_prec inclusive
