Description Dan Glastonbury 2023-04-06 16:28:04 PDT

Lexing did not correctly distinguish between an "abstract" and "concrete" floating point
literals. Eg. 124.0 vs 124.0f. This patch implements the distinction via tokens
AbstractFloatLiteral and FloatLiteral.

Also, not all cases of concrete literals specified with suffix 'f' were lexed
correctly. Added these cases and tests.
