Add -XBinaryLiterals language extension (re #9224)
Haskell2010 supports
- base-10 (prefix-less),
- base-8 (via `0[oO]`-prefix), and
- base-16 (via `0[xX]`-prefix) integer literals.
This commit adds syntax support for base-2 integer literals via the new `0[bB]`
prefix. The use of a `0b` prefix for indicating binary literals is known
from popular programming languages such as C++14, Perl, Python, Ruby, and Java.
This syntax extension is disabled by default and can be enabled via the
new `{-# LANGUAGE BinaryLiterals #-}` pragma and/or the new `-XBinaryLiterals`
This new extensions requires to upgrade the `ExtsBitmap` type from
`Word` to `Word64` as this adds a 33th flag which is not guaranteed to
fit into a `Word`.
