[AArch64][GlobalISel] Lower G_BUILD_VECTOR -> G_DUP
If we have
```
%vec = G_BUILD_VECTOR %reg, %reg, ..., %reg
```
Then lower it to
```
%vec = G_DUP %reg
```
Also update the selector to handle constant splats on G_DUP.
This will not combine when the splat is all zeros or ones. Tablegen-imported
patterns rely on these being G_BUILD_VECTOR.
Minor code size improvements on CTMark at -Os.
Also adds some utility functions to make it a bit easier to recognize splats,
and an AArch64-specific splat helper.

[AArch64][GlobalISel] Add a post-legalize combine for lowering vector-immediate G_ASHR/G_LSHR.
In order to select the immediate forms using the imported patterns, we need to
lower them into new G_VASHR/G_VLSHR target generic ops. Add a combine to do this
matching build_vector of constant operands.
With this, we get selection for free.

[AArch64][GlobalISel] Improve codegen for some constant vectors by using constant pool loads.
There's more smarts in AArch64ISelLowering that we don't have yet, but this
change incrementally improves some of the more common patterns. I think future
iterations will want to use some combination of PostLegalizerCombiner and the
selector to catch the other cases.

[AArch64][GlobalISel] Add isel support for vector G_ICMP and G_ASHR & G_SHL
The selection for G_ICMP is unfortunately not currently importable from SDAG
due to the use of custom SDNodes. To support this, this selection method has an
opcode table which has been generated by a script, indexed by various
instruction properties. Ideally in future we will have a GISel native selection
patterns that we can write in tablegen to improve on this.
For selection of some types we also need support for G_ASHR and G_SHL which are
generated as a result of legalization. This patch also adds support for them,
generating the same code as SelectionDAG currently does.
