This patch resolves the second part of PR target/112992, building upon
Hongtao Liu's solution to the first part.

The issue addressed by this patch is that when initializing vectors by
broadcasting integer constants, the compiler has the flexibility to
select the most appropriate vector mode to perform the broadcast, as
long as the resulting vector has an identical bit pattern.  For
example, the following constants are all equivalent:
V4SImode {0x01010101, 0x01010101, 0x01010101, 0x01010101 }
V8HImode {0x0101, 0x0101, 0x0101, 0x0101, 0x0101, 0x0101, 0x0101, 0x0101 }
V16QImode {0x01, 0x01, 0x01, 0x01, 0x01, 0x01, 0x01, 0x01, 0x01, ... 0x01 }
So instruction sequences that construct any of these can be used to
construct the others (with a suitable cast/SUBREG).

On x86_64, it turns out that broadcasts of SImode constants are preferred,
as DImode constants often require a longer movabs instruction, and
HImode and QImode broadcasts require multiple uops on some architectures.
Hence, SImode is always the equal shortest/fastest implementation.

Examples of this improvement, can be seen in the testsuite.

  1f:   c3                      retq

where according to Agner Fog's instruction tables broadcastd is slightly
faster on some microarchitectures, for example Knight's Landing.

This patch has been tested on x86_64-pc-linux-gnu with make bootstrap
and make -k check, both with and without --target_board=unix{-m32}
with no new failures.  Ok for mainline?
