Hi,
The expanding of widen-sum pattern always fails. The vectorizer expects the
operands to have the same size, while the current implementation of
widen-sum pattern dose not conform to this.
This patch implements the widen-sum pattern with vpadal. Change the vaddw
pattern to anonymous. Add widen-sum test cases for neon.
Can you please respin addressing James and Kyrill's comments ?

Hi,
Sorry for late response.
The pattern is rewritten to utilize neon_vpadal<sup><mode>'s "0"
constraints. Have run vect.exp and neon.exp in an armv7 board.
vect.exp has two new XFAILs:
XFAIL: gcc.dg/vect/slp-reduc-3.c scan-tree-dump-times vect "vectorizing
stmts using SLP" 1
XFAIL: gcc.dg/vect/slp-reduc-3.c -flto -ffat-lto-objects
scan-tree-dump-times vect "vectorizing stmts using SLP" 1
This is because widen-sum optimization precedes SLP. The xfail predicate
vect_widen_sum_hi_to_si becomes true when widen-sum is enabled.
neon.exp has four new XFAILs:
XFAIL: gcc.target/arm/neon/vect-widen-sum-char2short-s-d.c
scan-tree-dump-times vect "pattern recognized.*w\\+" 1
XFAIL: gcc.target/arm/neon/vect-widen-sum-char2short-s-d.c
scan-rtl-dump-times expand "UNSPEC_VPADAL" 1
XFAIL: gcc.target/arm/neon/vect-widen-sum-char2short-s.c
scan-tree-dump-times vect "pattern recognized.*w\\+" 1
XFAIL: gcc.target/arm/neon/vect-widen-sum-char2short-s.c
scan-rtl-dump-times expand "UNSPEC_VPADAL" 1
If the widen-sum pattern is successfully expanded, "w+" and
"UNSPEC_VPADAL" should appear in the dump file like other
vect-widen-sum-*.c tests. But vect-widen-sum-char2short-s[-d].c is
special because at tree level the signed operations will be converted
into unsigned operations, which destroy the widen-sum pattern. That is
due to the workaround of PR tree-optimization/25125. I just add xfail
following gcc.dg/vect/vect-reduc-pattern-2c.c.
