This patch adds support for generating LDPs and STPs of Q-registers.
This allows for more compact code generation and makes better use of the ISA.

It's implemented in a straightforward way by allowing 16-byte modes in the
sched-fusion machinery and adding appropriate peepholes in aarch64-ldpstp.md
as well as the patterns themselves in aarch64-simd.md.

It adds a new no_ldp_stp_qregs tuning flag.
I use it to restrict the peepholes in aarch64-ldpstp.md from merging the
operations together into PARALLELs. I also use it to restrict the sched fusion
check that brings such loads and stores together. This is enough to avoid
forming the pairs when the tuning flag is set.

I didn't see any non-noise performance effect on SPEC2017 on Cortex-A72 and Cortex-A53.

This patch makes pattern recognisers do their own checking for vector
types and target support.  Previously some recognisers did this
themselves and some left it to vect_pattern_recog_1.

Doing this means we can get rid of the type_in argument, which was
ignored if the recogniser did its own checking.  It also means
we create fewer junk statements.

From-SVN: r261791

This message is a long write-up for a patch that simply adds a common
routine for printing the "vector_foo_pattern: detected:" messages.

The reason for doing this is that some routines check for target support
themselves and some leave it to vect_pattern_recog_1.  Those that leave
it to vect_pattern_recog_1 currently print these "detected:" messages if
the statements have the right form, even if the pattern is eventually
discarded.  IMO that's useful, and a lot of existing scan tests rely on it.

However, a later patch makes patterns do their own testing, and stops
them creating pattern statements until the tests have passed.  This means
(a) they need to print the "detected:" message earlier and (b) the pattern
statement won't be around to print.

The patch therefore makes all routines print the original statement
rather than the pattern one.  That information isn't obvious otherwise,
whereas vect_pattern_recog_1 already prints the pattern statement
in the case of a successful match.  This also avoids the previous
situation in which a routine could print "detected:" and then
silently bail out before saying what had been detected.

vect_recog_dot_prod_pattern and vect_recog_sad_pattern both checked
whether the statement passed in had already been recognised as a

vectorizable_call stubs out the original scalar statement with
a dummy assignment to the same lhs, so that we don't leave any bogus
scalar calls around.  If the call is actually a pattern statement,
the code rightly took the lhs of the original bb statement:

  if (is_pattern_stmt_p (stmt_info))
    lhs = gimple_call_lhs (STMT_VINFO_RELATED_STMT (stmt_info));
  else
    lhs = gimple_call_lhs (stmt);

But it then associated the new statement with the stmt_vec_info of the
pattern statement rather than the bb statement, which meant we had two
stmt_vec_infos assigning to the same lhs.  This seems to be latent at
the moment but caused problems further into the series.

This patch is the first part of a series to fix to PR85694.
Later patches can make the pattern for a statement S2 reuse the
results of a PATTERN_DEF_SEQ statement attached to an earlier
statement S1.  Although vect_mark_stmts_to_be_vectorized handled
this fine, vect_analyze_stmt and vect_transform_loop both skipped the
PATTERN_DEF_SEQ for S1 if S1's main pattern wasn't live or relevant.

I couldn't wrap my head around the flow in vect_transform_loop,
so ended up moving the per-statement handling into a subroutine.
That makes the patch look bigger than it actually is.

The existing code allows only 4 vectors worth of ieee128 homogeneous
aggregates, but it should be 8.  This happens because at one spot it
is mistakenly qualified as being passed in floating point registers.


	PR target/86197
	* config/rs6000/rs6000.md (rs6000_discover_homogeneous_aggregate): An
	ieee128 argument takes up only one (vector) register, not two (floating
	point) registers.
