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.
Bootstrapped/regtested on aarch64-linux-gnu.

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.

Currently patchable area is at the wrong place. It is placed immediately
after function label, before both .cfi_startproc and ENDBR. This patch
adds UNSPECV_PATCHABLE_AREA for pseudo patchable area instruction and
changes ENDBR insertion pass to also insert patchable area instruction.
TARGET_ASM_PRINT_PATCHABLE_FUNCTION_ENTRY is defined to avoid placing
patchable area before .cfi_startproc and ENDBR.

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.

discrepancy between the current template depth and the template
depth of the original declaration, then adjust the 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.

When iterating over a class array use the bounds provided by the
transformed descriptor (in sym->backend_decl) instead of the original
bounds of the array (in the descriptor passed in the class _data)

(Analyze_Slice): Call Implicitly_Designated_Type to get the
designated type for an implicit dereference.

(Resolve_Call): Call Resolve_Indexed_Component last.
(Resolve_Entry): Call Resolve_Implicit_Dereference on the prefix.
(Resolve_Indexed_Component): Call Implicitly_Designated_Type to
get the designated type for an implicit dereference and
Resolve_Implicit_Dereference on the prefix at the end.

New_Copy_List by calls to the new routine
New_Copy_Separate_List.

New routines.

(New_Copy_Tree): Extend the machinery that detects syntactic
nodes to handle lists of indentifiers with field More_Ids;
otherwise such nodes are erroneously handled as semantic nodes.
Copy aspect specifications attached to nodes.
* sem_ch12.adb (Copy_Generic_Node): Protect reading attribute
Etype.

* sem_ch13.adb (Analyze_Aspect_Specifications): Do not set the
Has_Predicates flag when the Predicate_Failure aspect is seen.
It is legal (but pointless) to use this aspect without a
predicate. If we set the flag, we generate a half-baked
Predicate procedure, and if that procedure is nested, it causes
unnesting to crash.

packages.
