If a const vector all elements are same, the slide up is unnecessary.
gcc/ChangeLog:
* config/riscv/riscv-v.cc (shuffle_compress_patterns): Avoid
unnecessary slideup.

This new version fixes the issues discussed in v4 and also fixes an
issue that is described in the newly introduced
compute_validity_closure.
Bootstrapped on x86-64 and AArch64.
I also ran the GCC testsuite on x86-64, AArch64 and RISCV64. There are
no regressions except for
This is a new RTL pass that tries to optimize memory offset calculations
by moving them from add immediate instructions to the memory loads/stores.
For example it can transform this:
addi t4,sp,16
add t2,a6,t4
shl t3,t2,1
ld a2,0(t3)
addi a2,1
sd a2,8(t2)

Hi,RuoYao:
I think the test example memcpy-vec-3.c submitted in r14-3818 is
implemented incorrectly.
The 16-byte length in this test example will cause can_move_by_pieces to
return true when with '-mstrict-align', so no vector load instructions
will be generated.
