AMDGPU: Stop validating earlyclobber operands in assembler

This validation was introduced in D34003 for v_qsad/v_mqsad instructions
but it applies to all instructions with earlyclobber operands, which now
includes v_mad_i64/v_mad_u64.

In all these cases I do not think there is documentation saying that the
destination must not overlap the sources. Rather there are *some* cases
where the instruction may not function correctly if there is an overlap,
and we are using earlyclobber as a conservative way of preventing
codegen from generating those cases.

I think it is unhelpful for the assembler to enforce the earlyclobber
restriction because it prevents assembling cases where the programmer
knows that in fact the overlap is safe.

Resizing operations (e.g. sign extension) in DAG can go from any width

the only two legal vector sizes in HVX are a single vector and a pair
of vectors.
To simplify the legalization, such operations are expanded into steps
that only double/halve the type size, so that each such step can be fully
legalized on its own. The complication is that DAG will automatically
fold these steps back into one, e.g. sext(sext) -> sext. To prevent that
new HexagonISD nodes are introduced: TL_EXTEND and TL_TRUNCATE. Once

The type legalization is now common to aext/sext/zext/trunc and Hexagon-
specific ssat/usat nodes.

CostPriority to compare a pair of call sites:

2 years ago[lit] Implement DEFINE and REDEFINE directives
Joel E. Denny [Wed, 21 Sep 2022 15:32:05 +0000 (11:32 -0400)]
[lit] Implement DEFINE and REDEFINE directives

These directives define per-test lit substitutions.  The concept was
discussed at
<https://discourse.llvm.org/t/iterating-lit-run-lines/62596/10>.

For example, the following directives can be inserted into a test file
to define `%{cflags}` and `%{fcflags}` substitutions with empty
initial values, which serve as the parameters of another newly defined
`%{check}` substitution:

```
// DEFINE: %{cflags} =
// DEFINE: %{fcflags} =

// DEFINE: %{check} = %clang_cc1 %{cflags} -emit-llvm -o - %s | \
// DEFINE:            FileCheck %{fcflags} %s
```

The following directives then redefine the parameters before each use
of `%{check}`:

```
// REDEFINE: %{cflags} = -foo
// REDEFINE: %{fcflags} = -check-prefix=FOO
// RUN: %{check}

// REDEFINE: %{cflags} = -bar
// REDEFINE: %{fcflags} = -check-prefix=BAR
// RUN: %{check}
```

Of course, `%{check}` would typically be more elaborate, increasing
the benefit of the reuse.

One issue is that the strings `DEFINE:` and `REDEFINE:` already appear
in 5 tests.  This patch adjusts those tests not to use those strings.
Our prediction is that, in the vast majority of cases, if a test
author mistakenly uses one of those strings for another purpose, the
text appearing after the string will not happen to have the syntax
required for these directives.  Thus, the test author will discover
the mistake immediately when lit reports the syntax error.

This patch also expands the documentation on existing lit substitution
behavior.

integer types, but operate on fp registers. This can create some
inefficiencies in their lowering, where the registers are converted to

The previous code was rewriting all shape inquires on associate
construct entities to inquires on the associated expression or variable.

This is is incorrect because at the point of inquiry, some statement
between the association and the inquiry may have modified the expression
operands or variable in a way that changes its shapes or bounds.

For instance, in the example below, expression rewrites was previously
replacing `size(x, 1)` by `size(p, 1)` which is invalid if p is a
pointer.

```
associate(x => p + 1)
 call call_that_may_modify_p_shape()
 print *, size(x, 1)

to use the associated expression shape and bounds if and only if the

Commit de3445e0ef15c4209 (https://reviews.llvm.org/D132096) made

  // Create Vector with size of V, and each element of type Ty

Not quite sure why it uses the TypeStoreSize for the ElementSize,
but the new vector would only match in size with the old vector in
situations when the TypeStoreSize equals the TypeSize for Ty.
Therefore this patch adds a typeSizeEqualsStoreSize check as yet
another condition for allowing the the new type as a promotion
candidate.

Without this fix the new @test15 test would fail with an assert
like this:
