Fix bitfield accesses which straddle the boundary of the underlying
type.
- This generates somewhat less optimal code than before but this is
not hard to rectify once stable (at the cost of slightly more
complex code).
- This currently always uses little-endian ordering of the bitfield.
- This breaks the CodeGen/bitfield.c test because it was grepping for
hard-coded assembly instructions. Will fix once a better test case
is constructed (hard to do without execution).
- This fixes SingleSource/UnitTests/2006-01-23-InitializedBitField.c
and Regression/C/PR1386.c from the test suite.
