We have thorough coverage of predicates and scalar types,
so we just need a sampling of vector tests to show that
things are working or not with vectors types.

The Intel models need an extra 1uop for memory folded instructions, plus a lot of instructions take a non-default memory latency which should allow us to use the multiclass a lot more to tidy things up.

Summary:
LLVM defaults to the newer .init_array/.fini_array scheme for static
constructors rather than the less desirable .ctors/.dtors (the UseCtors
flag defaults to false). This wasn't being respected in the RISC-V
backend because it fails to call TargetLoweringObjectFileELF::InitializeELF with the the appropriate
flag for UseInitArray.
This patch fixes this by implementing RISCVELFTargetObjectFile and overriding its Initialize method to call
InitializeELF(TM.Options.UseInitArray).

Summary:
r327219 added wrappers to std::sort which randomly shuffle the container before sorting.
This will help in uncovering non-determinism caused due to undefined sorting
order of objects having the same key.
To make use of that infrastructure we need to invoke llvm::sort instead of std::sort.
Note: This patch is one of a series of patches to replace *all* std::sort to llvm::sort. Refer the comments section in D44363 for a list of all the required patches.

Currently when we build input sections list in linker script
we ignore all rel[a] sections. That was done to support
scripts like .rela.dyn : { *(.rela.data) } for emit relocs.
Though as a result following scripts were also silently ignored:
/DISCARD/ : { *(.rela.plt)
/DISCARD/ : { *(.rela.dyn)
and we produced output with this sections. That is not ideal.
The solution this patch suggests is simple: do not ignore synthetic
rel[a] sections. That way we can enable common discarding logic
for them and report a proper error.

Summary:
As the title says, this makes following code compile:
```
template<typename> struct Foo {};
Foo() -> Foo<void>;
Foo f; // ok
```
Thanks Nicolas Lesser for coining the fix.
