Power supports vector memory access with length (in bytes) instructions.
Like existing fully masking for SVE, it is another approach to vectorize
the loop using partially-populated vectors.
As Richard Sandiford suggested, we should share the codes in approaches
with partial vectors if possible. This patch is to:
1) factor out two functions:
- vect_min_prec_for_max_niters
- vect_known_niters_smaller_than_vf.
2) rename four functions:
- vect_iv_limit_for_full_masking
- check_load_store_masking
- vect_set_loop_condition_masked
- vect_set_loop_condition_unmasked
3) rename macros LOOP_VINFO_MASK_COMPARE_TYPE and LOOP_VINFO_MASK_IV_TYPE.

This patch uses parameter packs to define insn_gen_fn::operator().
I guess in some ways it's C++-ification for its own sake, but it does
make things simpler and removes the current artificial limit of 16
arguments.
Note that the call is still strongly typed: all arguments have to have
implicit conversions to rtx. Error messages for bad arguments look
reasonable.
I'm sure there are more elegant ways of getting the function type,
but this version at least fits on one line, so I didn't try too
hard to find an alternative.

This fixes two issues in our handling of constrained class template
friend declarations.
The first issue is that we fail to set the constraints on the injected
class template declaration during tsubst_friend_class.
The second issue is that the template parameter levels within the parsed
constraints of a class template friend declaration are shifted if the
enclosing class is a template, and this shift leads to spurious
constraint mismatch errors in associate_classtype_constraints if the
friend declaration refers to an already declared class template.

The current code assumes that if the next character in the stream is
equal to the delimiter then we stopped because we saw that delimiter,
and so discards it. But in the testcase for the PR we stop because we
reached the maximum number of characters, and it's coincidence that the
next character equals the delimiter. We should not discard the next
character in that case.
The fix is to check that we haven't discarded __n characters already,
instead of checking whether the next character equals __delim. Because
we've already checked for EOF, if we haven't discarded __n yet then we
know we stopped because we saw the delimiter. On the other hand, if the
next character is the delimiter we don't know if that's why we stopped.
