847982c6bf Handle bit-field test after shift/mask 
Previously, bit-field tests were incorrectly combined with load in
`if (x.bitfield)`.  Delay the test until after the shift/mask
is done.  Still combine tests with load if no shift/mask is required.

Fixes #1139

3df6c383c0 Add support for static_assert 
Add C11's _Static_assert and static_assert macro.

This is like #error, but is handled at a later stage
of translation, so it is possible to check sizes of
types, values of enums, etc.

2d5fd0fc63 Use char ops if possible for bit-field loads 
Set CF_FORCECHAR and change type to char once we have
shifted into a char.

This saves some unnecessary ldx #0 instructions.
