[ARM][AArch64][DAG] Reenable post-legalize store merge
...
Reenable post-legalize stores with constant merging computation and
corresponding test case.
* Properly truncate store merge constants
* Disable merging of truncated stores floating points
* Ensure merges of constant stores into a single vector are
constructed from legal elements.

[DAG] Do MergeConsecutiveStores again before Instruction Selection
...
Summary:
Now that store-merge is only generates type-safe stores, do a second
pass just before instruction selection to allow lowered intrinsics to
be merged as well.

[AArch64] Enable merging of adjacent zero stores for all subtargets.
...
This optimization merges adjacent zero stores into a wider store.
e.g.,
strh wzr, [x0]
strh wzr, [x0, #2 ]
; becomes
str wzr, [x0]
e.g.,
str wzr, [x0]
str wzr, [x0, #4 ]
; becomes
str xzr, [x0]
Previously, this was only enabled for Kryo and Cortex-A57.
