This patch prevents the `llvm.masked.gather` and `llvm.masked.scatter` intrinsics to be scalarized when invoked on scalable vectors.
The change in `Function.cpp` is needed to prevent the warning that is raised when `getNumElements` is used in place of `getElementCount` on `VectorType` instances. The tests guards for regressions on this change.
The tests makes sure that calls to `llvm.masked.[gather|scatter]` are still scalarized when:
# the intrinsics are operating on fixed size vectors, and
# the compiler is not targeting fixed length SVE code generation.

'require<globals-aa>' is needed to make globals-aa work in NPM, since
globals-aa is a module analysis but function passes cannot run module
analyses on demand.
So don't skip translating alias analyses to 'require<>'.

WeakRefDirective should specify a directive to declare "a global as being a weak undefined symbol".
The directive used by AMDGPU was incorrect - ".weakref" was intended for other purposes.
The correct directive is ".weak" and it is already defined as default for ELF.
So the redefinition was removed.

Fix lowering and instruction selection for v3x16 types
and enable InstCombine to emit them.
This patch only implements it for the selection dag.
GlobalISel tests in GlobalISel/llvm.amdgcn.image.load.1d.d16.ll and
GlobalISel/llvm.amdgcn.image.store.2d.d16.ll still don't work.

Pre-gfx10 all MODE-setting instructions were S_SETREG_B32 which is
marked as having unmodeled side effects, which makes the machine
scheduler treat it as a barrier. Now that we have proper implicit $mode
operands we can use a no-side-effects S_SETREG_B32_mode pseudo instead
for setregs that only touch the FP MODE bits, to give the scheduler more
freedom.

Now that we're getting better at combining shuffles of different vector widths, this can now be performed as part of the standard target shuffle combines and isn't required for cleanup.
Exposed a minor issue in combineX86ShufflesRecursively where we failed to check if a shuffle's src ops were simple types.

assert(OutlinedFunctionCost >= Cloner.OutlinedRegionCost && "Outlined function cost should be no less than the outlined region") getting triggered in computeBBInlineCost.
Intrinsics like "assume" are considered regular function calls while computing costs.
This patch enables computeBBInlineCost to queries TTI for intrinsic call cost.

We've fixed the case where this could return an instruction after the
given instruction, but also means that we can falsely return a
'unique' def when they could be one coming from the backedge of a
loop.

Clear the CurrentPredicate when we find an instruction which would
completely overwrite the VPR. This fix essentially means we're back

`section-symbols.test` tests how we print section symbols in
different situations.
We might have 2 different cases:
1) A named STT_SECTION symbol.
2) An unnamed STT_SECTION symbol.
Usually section symbols have no name and then `--symbols` uses their
section names when prints them. If symbol has a name, then it is used.
For `--relocations` we also want to have this logic probably,
but currently we always ignore symbol names and always use section names.
It is not consistent with GNU readelf and with our logic for `--symbols`.
This patch refines testing to document the existent behavior and improve
coverage.

GlobPattern::isTrivialMatchAll() returns true for the GlobPattern "*"

This can be used to avoid performing expensive preparation of the input

This is needed to support assumed size array of fortran which can have missing upperBound/count
, contrary to current DISubrange support.
Example:
subroutine sub (array1, array2)
integer :: array1 (*)
integer :: array2 (4:9, 10:*)
array1(7:8) = 9
array2(5, 10) = 10
end subroutine
Now the validation check is relaxed for fortran.

This matches how such options are most commonly defined in other tools.
This was pointed out in an earlier review a few months ago, that
the llvm-rc td entries felt shouty.
The INCLUDE option is renamed to includepath, to avoid clashing with
