Summary:
Implemented a DenseStringsElements attr for handling arrays / tensors of strings. This includes the
necessary logic for parsing and printing the attribute from MLIR's text format.
To store the attribute we perform a single allocation that includes all wrapped string data tightly packed.
This means no padding characters and no null terminators (as they could be present in the string). This
buffer includes a first chunk of data that represents an array of StringRefs, that contain address pointers
into the string data, with the length of each string wrapped. At this point there is no Sparse representation
however strings are not typically represented sparsely.

This revision removes the multi use-list to ensure that each result gets its own. This decision was made by doing some extensive benchmarking of programs that actually use multiple results. This results in a size increase of 1-word per result >1, but the common case of 1-result remains unaffected. A side benefit is that 0-result operations now shrink by 1-word.

[SVE] Remove VectorType::isScalable()
Summary:
* This is a property of the instance of VectorType. If
isa<ScalableVectorType>(T) is true, then T->isScalable() would have
returned true and vice-versa. Most code that checks this function uses
the result to bail out if a vector is a scalable vector. This code will
be cleaner if it just calls isa<ScalableVectorType>(T)

[flang] Compute sizes and offsets for symbols
Summary:
Add size and offset properties to symbols, representing their byte size

Add size and align properties to scopes so that they are available for
scopes representing derived types.
Add ComputeOffsets pass over the symbol table to fill in those fields.
Compute descriptor size based on rank and length parameters. Extract
DerivedTypeSpec::NumLengthParameters from DynamicType::RequiresDescriptor
to share the code.
Add Scope::GetSymbols to get symbols in canonical order.
compute-offsets.cpp and mod-file.cpp both need to process symbols in the
order in which they are declared. Move the collecting of those symbols
into Scope so that it can be shared.
Add symbol size and offset to output of `-fdebug-dump-symbols` and use
that in some tests.
Still to do:
- make size and alignment rules configurable based on target
- use offsets to check EQUIVALENCE statements

Make "#pragma clang attribute" support uninitialized attribute.
Summary:
When using -ftrivial-auto-var-init=* options to initiate automatic
variables in a file, to disable initialization on some variables,
currently we have to manually annotate the variables with uninitialized
attribute, such as
int dont_initialize_me __attribute((uninitialized));
Making pragma clang attribute to support this attribute would make
annotating variables much easier, and could be particular useful for
bisection efforts, e.g.
void use(void*);
void buggy() {
int arr[256];
int boom;
float bam;
struct { int oops; } oops;
union { int oof; float aaaaa; } oof;
use(&arr);
use(&boom);
use(&bam);
use(&oops);
use(&oof);

if the old `sub` sticks around then the transform is not only
not a unlikely win, but a likely regression, since we likely
now extended live range and use count of both of the `sub` operands,
as opposed to just the result of `sub`.
As Kostya Serebryany notes in post-commit review in

this indeed can degrade final assembly,
increase register pressure, and spilling.

AMDGPU: Change pre-gfx9 implementation of fcanonicalize to mul
If f32 denormals were enabled pre-gfx9, we would still try to
implement this with v_max_f32. Pre-gfx9, these instructions ignored
the denormal mode and did not flush. Switch to the multiply form for
f32 as a workaround which should always work in any case.
This fixes conformance failures when the library implementation of
fmin/fmax were accidentally not inlined, forcing the assumption of no
flushing on targets where denormals are not enabled by default. This
is a workaround, since really we should not be mixing code with
different FP mode expectations, but prefer the lowering that will work
in any mode.
Now this will always use max to implement canonicalize on gfx9+. This
is only really beneficial for f64. For f32/f16 it's a neutral choice
(and worse in terms of code size in 1 case), but possibly worse for
the compiler since it does add an extra register use operand. Leave
this change for later.
