[DAGCombiner] (REAPPLIED) Add vector demanded elements support to computeKnownBits
Currently computeKnownBits returns the common known zero/one bits for all elements of vector data, when we may only be interested in one/some of the elements.
This patch adds a DemandedElts argument that allows us to specify the elements we actually care about. The original computeKnownBits implementation calls with a DemandedElts demanding all elements to match current behaviour. Scalar types set this to 1.
The approach was found to be easier than trying to add a per-element known bits solution, for a similar usefulness given the combines where computeKnownBits is typically used.
I've only added support for a few opcodes so far (the ones that have proven straightforward to test), all others will default to demanding all elements but can be updated in due course.
DemandedElts support could similarly be added to computeKnownBitsForTargetNode in a future commit.

Everywhere that currently uses it defines the operand to have the same

conflicts, and its up evaluating to the wrong thing. For the
real encoding classes,
let Inst{16} = !if(ps.has_glc, glc, ?); was not being evaluated

Don't leave unused divs/rems sitting around in BypassSlowDivision.
Summary:
This "pass" eagerly creates div and rem instructions even when only one
is needed -- it relies on a later pass (machine DCE?) to clean them up.
This is problematic not just from a cleanliness perspective (this pass
is running during CodeGenPrepare, so should leave the IR in a better
state), but it also creates a problem for instruction selection. If we
always have a div+rem, isel will always select a divrem instruction (if
possible), even when a single div or rem would do.
Specifically, in NVPTX, we want to compute rem from the output of div,
if available. But if a div is not available, we want to leave the rem
alone. This transformation is overeager if div is always available.
Because this code runs as part of CodeGenPrepare, it's nontrivial to
write a test for this change. But this will effectively be tested by
a later patch which adds the aforementioned change to NVPTX isel.

Handle non-~0 lane masks on live-in registers in LivePhysRegs
When LivePhysRegs adds live-in registers, it recognizes ~0 as a special
lane mask indicating the entire register. If the lane mask is not ~0,
it will only add the subregisters that overlap the specified lane mask.
The problem is that if a live-in register does not have subregisters,
and the lane mask is not ~0, it will not be added to the live set.
(The given lane mask may simply be the lane mask of its register class.)
If a register does not have subregisters, add it to the live set if
the lane mask is non-zero.

It's possible to have a use of the private resource descriptor or

We already read the flags out of the summary when writing the summary

This is an NFC change for now since the flags computed on the fly from

[Error] Unify +Asserts/-Asserts behavior for checked flags in Error/Expected<T>.
(1) Switches to raw pointer and bitmasking operations for Error payload.
(2) Always includes the 'unchecked' bitfield in Expected<T>, even in -Asserts.
(3) Always propagates checked bit status in move-ops for both classes, even in
-Asserts.
This should allow debug programs to link against release libraries without
encountering spurious 'unchecked error' terminations.
Error checks still aren't verified in release mode so this doesn't introduce
any new control flow, but it does require new bit-masking ops in release mode
to preserve the flag values during move ops. I expect the overhead to be
minimal, but if we discover any corner cases where it matters we could fix
this by making flag propagation conditional on a new build option.

[CUDA] [AST] Allow isInlineDefinitionExternallyVisible to be called on functions without bodies.
Summary:
In CUDA compilation, we call isInlineDefinitionExternallyVisible (via
getGVALinkageForFunction) on functions while parsing their definitions.
At the point in time when we call getGVALinkageForFunction, we haven't
yet added the body to the function, so we trip this assert. But as far
as I can tell, this is harmless.
To work around this, we add a new flag to FunctionDecl, "WillHaveBody".
There was other code that was working around the existing assert with a
really awful hack -- this change lets us get rid of that hack.
