Record::getValues returns ArrayRef which has a cast operator
to std::vector, as a result a temporary vector is created
if the type of the variable is const std::vector&
that is suboptimal in this case.

Summary:
When broadcasting from the constant pool its useful to print out the final vector similar to what we do for normal moves from the constant pool.
I changed only a couple tests that were broadcast focused. One of them had been previously hand tweaked after running the script so that it could check the constant pool declaration. But I think this patch makes that unnecessary now since we can check the comment instead.

symbol resolver argument.
De-templatizing the symbol resolver is part of the ongoing simplification of
ORC layer API.
Removing the memory management argument (and delegating construction of memory
managers for RTDyldObjectLinkingLayer to a functor passed in to the constructor)
allows us to build JITs whose base object layers need not be compatible with
RTDyldObjectLinkingLayer's memory mangement scheme. For example, a 'remote
object layer' that sends fully relocatable objects directly to the remote does
not need a memory management scheme at all (that will be handled by the remote).

Previously, if a basic block ended with a FRMIDX instruction, we would
end up doing something like this.
*std::next(MBB.end())
Which would hit an error:
"Assertion `!NodePtr->isKnownSentinel()' failed."

The patch makes SoftenFloatResult/Operand logic just the same as all other legalization routines have: SoftenFloatResult() now fills the SoftenFloats map and SoftenFloatOperand() perform all needed replacements. This prevents softening mashinery from leaving stale entries in SoftenFloats map (that resulted in errors during the legalize type checking) and clarifies softening. The patch replaces https://reviews.llvm.org/D29265.

Summary:
This is a follow-up on D34077. Elena observed that the
correctness of the code relies on isPowerOf2(0) returning false.
Adding a test to cover this corner-case.

Summary:
Add a combine for creating a truncate to replace a build_vector composed of extracts with
indices that form a stride-2^N series.
Example:
v8i32 V = ...
v4i32 build_vector((extract_elt V, 0), (extract_elt V, 2), (extract_elt V, 4), (extract_elt V, 6))
-->
v4i32 truncate (bitcast V to v4i64)

These all used 'CHECK-NOT' which isn't necessary if we have complete checks.
There were also over-specifications in the RUN params such as CPU model.

We assumed the constant was a scalar when creating the replacement operand.
Also, improve tests for this fold and move the tests for this fold to their own file.
I'll move the related and missing tests to this file as a follow-up.

I noticed this missed bswap optimization in the CGP memcmp() expansion,
and then I saw that we don't have the fold in InstCombine.

We are combining shuffles to bit shifts before unary permutes, which means we can't fold loads plus the destination register is destructive
