Reviewers: Sven Panne,
Message:
As discussed.
Some of these changes should not affect object layout at all; in some other
cases I took the opportunity to move more things into the bitfield. No
change in
behavior is intended, except possibly in situations where the compiler
wasn't
doing what we thought it was doing.
There are two more occurrences of "_ : [0-9]" in src/compiler/ which I've
left
alone for now; other than that the entire codebase should now be uniformly
using
BitField<...> for packing fields.
Please take a look.
Description:
Replace C++ bitfields with our own BitFields
Shave this yak from orbit, it's the only way to be sure.
