Subject: [PATCH 1/2] [Clang] Fix __builtin_clear_padding() for bitfields
This patch fixes the padding clearing logic for bitfields.
The padding clearing logic for bitfields is wrong for these cases:
- Over-sized bitfields don't have their padding bits recognised as
such.
- In big endian mode, the occupied bits are wrongly determined because
the different byte order is dismissed.
A big number of new tests have also been added to cover many different
scenarios that involve bitfields. Preexisting tests had their check
patterns regenerated with the updater script.
Assisted-by: Codex. Used to help debugging and to generate tests.
