Check fields from `MDLocalVariable` and `MDGlobalVariable` and change
the accessors to downcast to the right types. `getType()` still returns
`Metadata*` since it could be an `MDString`-based reference.
Since local variables require non-null scopes, I also updated `LLParser`
to require a `scope:` field.
A number of testcases had grown bitrot and started failing with this
patch; I committed them separately in r233349. If I just broke your
out-of-tree testcases, you're probably hitting similar problems (so have
a look there).

Added a new boolean CMake flag, LLVM_INSTALL_UTILS. When set,
the 'install' target will include in the bin directory the
utils binaries - e.g. FileCheck. This mirrors the autoconfig
behavior.
Test Plan:
Locally verified that utils binaries are copied when flag is set,
and not copied when flag is not set.

Dropping old debug format requires the entire module to be read upfront.
This was failing only with the gold plugin, but that is just because
llvm-link was not upgrading metadata.
The new testcase using llvm-link shows the problem.

The last user of this code vanished with r223368, but this function still was
around being executed on every process start, allocating some memory and then
never being used again. No functional change.
Also avoids occasional complaints about the benign leak in this function, like
PR23037.

This re-adds float2int to the tree, after fixing PR23038. It turns
out the argument to APSInt() is true-if-unsigned, rather than
true-if-signed :(. Added testcase and explanatory comment.

"Fix the MachineScheduler's logic for updating ready times for in-order.
Now the scheduler updates a node's ready time as soon as it is
scheduled, before releasing dependent nodes."
This fix was only made in one variant of the ScheduleDAGMI driver.
Francois de Ferriere reported the issue in the other bit of code where
it was also needed.
I never got around to coming up with a test case, but it's an
obvious fix that shouldn't be delayed any longer.
I'll try to refactor this code a little better.
I did verify performance on a wide variety of targets and saw no
negative impact with this fix.

The assertion here was more expensive then it needed to be. We're only inserting allocas in the entry block, so we only need to consider ones in the entry block.

This was discussed a while back and I left it optional for migration. Since it's been far more than the 'week or two' that was discussed, time to actually make this manditory.

This patch adds support for explicitly provided spill slots in the GC arguments of a gc.statepoint. This is somewhat analogous to gcroot, but leverages the STATEPOINT MI node and StackMap infrastructure. The motivation for this is:
1) The stack spilling code for gc.statepoints hasn't advanced as fast as I'd like. One major option is to give up on doing spilling in the backend and do it at the IR level instead. We'd give up the ability to have gc values in registers, but that's a minor cost in practice. We are not neccessarily moving in that direction, but having the ability to prototype such a thing cheaply is interesting.
2) I want to port the gcroot lowering to use the statepoint infastructure. Given the metadata printers for gcroot expect a fixed set of stack roots, it's easiest to just reuse the explicit stack slots and pass them directly to the underlying statepoint.
I'm holding off on the documentation for the new feature until I'm reasonable sure this is going to stick around.

This test returns nonnative integer types which aren't supported on all targets.
The real issue with the SelectionDAG scheduler is with x86 EFLAGS.

We don't have any logic to emit those tables yet, so the SDAG lowering
of this intrinsic is just a stub. We can see the intrinsic in the
prepared IR, though.

It can happen (by line CurSU->isPending = true; // This SU is not in
AvailableQueue right now.) that a SUnit is mark as available but is
not in the AvailableQueue. For SUnit being selected for scheduling
both conditions must be met.
This patch mainly defensively protects from invalid removing a node
from a queue. Sometimes nodes are marked isAvailable but are not in
the queue because they have been defered due to some hazard.

Fix testcases whose variables are invalid. I'm working on a patch that
adds `Verifier` checks for `MDLocalVariable` (and `MDGlobalVariable`),
and these failed because:
- `scope:` fields need to point at `MDLocalScope` and can't be null.
- `file:` fields need to point at `MDFile`.
- `inlinedAt:` fields need to point at `MDLocation`.

declaration name so that we mark declarations for emission in
a deterministic order (and in turn give them deterministic IDs).
This is the last for loop or data structure I can find by inspection of
the AST writer which doesn't use a deterministic order.
Found by inspection, no test case.

Previously, if the expr list parsed fine but the expr to the left of the
open parenthesis was invalid (when parsing the suffix of a
postfix-expression), the parsed expr list was just ignored.
Fixes PR23005.
