Clang 19 is now more strict about undefined integral expressions used as
constants in enum, which results in errors compiling java/openjdk8,
similar to:
/wrkdirs/usr/ports/java/openjdk8/work/jdk8u-jdk8u422-b05.1/hotspot/src/share/vm/oops/cpCache.hpp:195:34:
error: expression is not an integral constant expression
195 | option_bits_mask = ~(((-1) << tos_state_shift) |
(field_index_mask | parameter_size_mask))

In openjdk11 and later, the (-1) constants have been replaced by the
unsigned variant (~0u), which fixes these errors.
