Some URI scheme needs the hint path to do a correct resolution, we pass
one of the open files as hint path.
This is not perfect, and it might not work for opening files across
project, but it would fix a bug with our internal scheme.
in the long run, removing URIs from all the index internals is a more proper fix.

The PrepareForLTO stage of LoopRotate tries to avoid unrolling loops
with calls that might be inlined later. See D94232 where this was
introduced.
We didn't catch all occurances of the LoopRotatePass in the New Pass
Manager, so the original regression in astar returned with the pass
manager switch.
This patch documents command line parsing in `-cc1`, `CompilerInvocation` and the marshalling infrastructure for command line options.

Fold shuffle(bop(shuffle(x,y),shuffle(z,w)),bop(shuffle(a,b),shuffle(c,d))) -> bop(shuffle(x,y),shuffle(z,w)),bop(shuffle(a,b),shuffle(c,d))
Attempt to fold from a shuffle of a pair of binops to a binop of shuffles, as long as one/both of the binop sources are also shuffles that can be merged with the outer shuffle. This should guarantee that we remove one binop without introducing any additional shuffles.
Technically there's potential for a merged shuffle's lowering to be poorer than the original shuffle, but it could also be better, and I'm not seeing any regressions as long as we keep the 'don't merge splats' rule already present in MergeInnerShuffle.
This expands and generalizes an existing X86 combine and attempts to merge either of each binop's sources (with an on-the-fly commutation of the shuffle mask) - we couldn't do that in the x86 version as it had to stay in a form that DAGCombine's MergeInnerShuffle would still recognise.
Fixes issue raised by @saugustine in rG5aa8f4c0843a where we were failing to replace null shuffle operands from MergeInnerShuffle to UNDEFs.

With enough cores, the slowest tests can significantly change the total testing time if they happen to run late. With this change, a test suite can improve performance (for high-end systems) by listing just a few of the slowest tests up front.

The helper function isBoolSGPR is too aggressive when determining
when a v_cndmask can be skipped on a boolean value because the
function does not check the operands of and/or/xor.
This can be problematic for the Add/Sub combines that can leave
bits set even for inactive lanes leading to wrong results.
Fix this by inspecting the operands of and/or/xor recursively.

Some test systems do not use lit for test discovery but only for its
substitution and test selection because they use another way of managing
test collections, e.g. CTest. This forces those tests to be invoked with
lit --no-indirectly-run-check. When a mix of lit version is in use, it
requires to detect the availability of that option.
This commit provides a new config option standalone_tests to signal a
directory made of tests meant to run as standalone. When this option is
set, lit skips test discovery and the indirectly run check. It also adds
the missing documentation for --no-indirectly-run-check.

This is a follow up D96600 and cleans up most calls to
getPreferredAddresingMode. I.e., we really don't need to query the same things
again and again, but get the preferred addressing mode once for each loop. So
this should be a lot friendlier for compile times, especially if we start
implementing getPreferredAddresingMode.

We can't construct a working unique_function from an object that's not callable
with the right types, so don't allow deduction to succeed.
This avoids some ambiguous conversion cases, e.g. allowing to overload
on different unique_function types, and to conversion operators to
unique_function.
std::function and the any_invocable proposal have these.

This patch proposes how to deal with RISC-V vector frame objects. The
layout of RISC-V vector frame will look like
|---------------------------------|
| scalar callee-saved registers |
|---------------------------------|
| scalar local variables |
|---------------------------------|
| scalar outgoing arguments |
|---------------------------------|
| RVV local variables && |
| RVV outgoing arguments |
|---------------------------------| <- end of frame (sp)
If there is realignment or variable length array in the stack, we will use
frame pointer to access fixed objects and stack pointer to access
non-fixed objects.
|---------------------------------| <- frame pointer (fp)
| scalar callee-saved registers |
|---------------------------------|
| scalar local variables |
|---------------------------------|
| ///// realignment ///// |
|---------------------------------|
| scalar outgoing arguments |
|---------------------------------|
| RVV local variables && |
| RVV outgoing arguments |
|---------------------------------| <- end of frame (sp)
If there are both realignment and variable length array in the stack, we
will use frame pointer to access fixed objects and base pointer to access
non-fixed objects.
|---------------------------------| <- frame pointer (fp)
| scalar callee-saved registers |
|---------------------------------|
| scalar local variables |
|---------------------------------|

In this version, we do not save the addresses of RVV objects in the
stack. We access them directly through the polynomial expression
(a x VLENB + b). We do not reserve frame pointer when there is any RVV
object in the stack. So, we also access the scalar frame objects through the
polynomial expression (a x VLENB + b) if the access across RVV stack
area.
