This patch series addresses PR 100757 and 101325 by representing
vectors of predicates (MVE VPR.P0 register) as vectors of booleans
rather than using HImode.
As this implies a lot of mostly mechanical changes, I have tried to
split the patches in a way that should help reviewers, but the split
is a bit artificial.
Patches 1-3 add new tests.
Patches 4-6 are small independent improvements.
Patch 7 implements the predicate qualifier, but does not change any
builtin yet.
Patch 8 is the first of the two main patches, and uses the new
qualifier to describe the vcmp and vpsel builtins that are useful for
auto-vectorization of comparisons.
Patch 9 is the second main patch, which fixes the vcond_mask expander.
Patches 10-13 convert almost all the remaining builtins with HI
operands to use the predicate qualifier. After these, there are still
a few builtins with HI operands left, about which I am not sure: vctp,
vpnot, load-gather and store-scatter with v2di operands. In fact,
patches 11/12 update some STR/LDR qualifiers in a way that breaks
these v2di builtins although existing tests still pass.
