Peter Collingbourne acf005676e Change the cap on the amount of padding for each vtable to 32-byte (previously it was 128-byte)
We tested different cap values with a recent commit of Chromium. Our results show that the 32-byte cap yields the smallest binary and all the caps yield similar performance.
Based on the results, we propose to change the cap value to 32-byte.

The tests in this directory use a common convention for exercising the
functionality associated with bit sets of different sizes. When certain
macros are defined the tests instantiate classes that force the bit sets
to be of certain sizes.

- B32 forces 32-bit bit sets.
- B64 forces 64-bit bit sets.
- BM forces memory bit sets.
