This attempts to move all tools over to using `add_llvm_library` for
better consistency. After doing this, I noticed it ended up as nearly a
reimplementation of https://reviews.llvm.org/rL342148, which later got
reverted in r342336 (b09a8c9bd9).
With ccache and ninja on a large core machine (40), I haven't run into
build errors, so I'm hopeful it's better now, though it doesn't seem to
be any different / new.

getSize and setSize both use unsigned. So size_t doesn't
increase range here and might get truncated if passed to
setSize.
Also not sure why EmitVBRValue was returning uint64_t, but used
an unsigned to supply the value.

If a downstream project using lit needs time for transition,
add the following to `lit.local.cfg`:
```
from lit.llvm.subst import ToolSubst
fc = ToolSubst('FileCheck', unresolved='fatal')
config.substitutions.insert(0, (fc.regex, 'FileCheck --allow-unused-prefixes'))

This ensures that we'll match immediates consistently regardless
of whether we match them as a standalone splat or as part of
another operation.
While I was there I added complexities to the simm5/uimm5 patterns so
we didn't have to assume that the 1 on the non-immediate was lower
than what tablegen inferred.
I had to make a minor tweak to tablegen to fix one place that
didn't expect to see a ComplexPattern that wasn't a "leaf".

This patch adds a pass to replace calls to vector intrinsics
(i.e., LLVM intrinsics operating on vector operands) with
calls to a vector library.
Currently, calls to LLVM intrinsics are only replaced with
calls to vector libraries when scalar calls to intrinsics are
vectorized by the Loop- or SLP-Vectorizer.
With this pass, it is now possible to replace calls to LLVM
intrinsics already operating on vector operands, e.g., if
such code was generated by MLIR. For the replacement,
information from the TargetLibraryInfo, e.g., as specified
via -vector-library is used.

We do ship those headers, so the directory name should not be something

cl::ZeroOrMore allows the option to be specified multiple times, which makes
downstream projects possible to specify a default value in lit configuration
while some tests can override the value.
The switch controls both unused prefix warnings, and warnings about
functions which differ under different runs for a prefix, and, thus, end
up not having asserts for that prefix.
(If the latter case spans to all functions, then the former case kicks
in)
The switch is on by default, and can be disabled.

This patch is a follow up to D94821 to ensure the correct behavior of the
general directive structure checker.
This patch add the generation of the Enter function declaration for clauses in
the TableGen backend.
This helps to ensure each clauses declared in the TableGen file has at least
a basic check.

This primarily occurs with isel patterns using vnot. This reduces
the number of variants in the isel tables.
We generally canonicalize build_vectors of constants to the RHS. I think
we might fail if there is a bitcast on the build_vector, but that
should be easy to fix if we can find a case. Usually the
bitcast is introduced by type legalization or lowering. It's
likely canonicalization would have already occured.
We already used emplace_back in at least one other place so be
consistent.
AddPatternToMatch already took PTM as an rvalue reference, but
we need to use std::move again to move it into the PatternToMatch
vector.
Use vector::swap instead of copying to a local vector and clearing
the original. We can just swap into the just created local vector
instead which will move the pointers and not the data.
Use std::move in another place to avoid a copy.

This patch allows targets to define multiple cost
values for each register so that the cost model
can be more flexible and better used during the
register allocation as per the target requirements.
For AMDGPU the VGPR allocation will be more efficient
if the register cost can be associated dynamically
based on the calling convention.
