ce19d7b84f Made use of Travis CI's Windows support. 
At least for now there seems to be no point in trying to build the libraries (and run the tests) on Windows. Rather we only want to check that the MSVC solution is still valid.

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.

a2561d07f3 Remove special-case bit-field width code 
cbb33f8 restricted allowed bit-field types to int,
so this is equivalent for now, but forward-compatible.

Fixes FIXME

Also move the int type check before parsing the colon.

74dda01919 Add test that plain int bitfields are unsigned 
We want to make sure this doesn't change when #1095 is fixed;
unsigned is much more efficient.
