Assume that switch on an enum doesn't follow an implicit default
skipping all cases when all enum values are covered by cases.
Fixes various false positives from -Wanalyzer-use-of-uninitialized-value
such as this one seen in Doom:

In the before-IRA era, ORDER_REGS_FOR_LOCAL_ALLOC was called for each
function in Xtensa, and there was register allocation table reordering
for leaf functions to compensate for the poor performance of local-alloc.
Today the adjustment hook is still called via its alternative
ADJUST_REG_ALLOC_ORDE
