[MachineCombiner] Lift same-bb restriction for reassociable ops.

This patch relaxes the restriction that both reassociate operands must
be in the same block as the root instruction.

The comment indicates that the reason for this restriction was that the
operands not in the same block won't have a depth in the trace.

I believe this is outdated; if the operand is in a different block, it
must dominate the current block (otherwise it would need to be phi),
which in turn means the operand's block must be included in the current
rance, and depths must be available.

There's a test case (no_reassociate_different_block) added in
70520e2f1c5fc4 which shows that we have accurate depths for operands
defined in other blocks.

Takuya Shimizu [Fri, 13 Jan 2023 13:20:14 +0000 (08:20 -0500)]
Fix -Wlogical-op-parentheses warning inconsistency for const and constexpr values

When using the && operator within a || operator, both Clang and GCC
produce a warning for potentially confusing operator precedence.
However, Clang avoids this warning for certain patterns, such as
a && b || 0 or a || b && 1, where the operator precedence of && and ||
does not change the result.

However, this behavior appears inconsistent when using the const or
constexpr qualifiers. For example:

bool t = true;
bool tt = true || false && t; // Warning: '&&' within '||'
const bool t = true;
bool tt = true || false && t; // No warning
const bool t = false;
bool tt = true || false && t; // Warning: '&&' within '||'

The second example does not produce a warning because
true || false && t matches the a || b && 1 pattern, while the third one
does not match any of them.

This behavior can lead to the lack of warnings for complicated
constexpr expressions. Clang should only suppress this warning when
literal values are placed in the place of t in the examples above.

This patch adds the literal-or-not check to fix the inconsistent
warnings for && within || when using const or constexpr.

test.a {
  %0 = test.b() {eligible = true}

}
```

Afterwards:
```
%0 = test.b() {eligible = true}
test.a {
  yield %0
}
```

The pattern is an `OpRewritePattern<OpA>`. For some reason, `test.a` is not on the GreedyPatternRewriter's worklist. E.g., because no pattern could be applied and it was removed. Now, another pattern updates `test.b`, so that `eligible` is changed from `true` to `false`. The `OpRewritePattern<OpA>` could now be applied, but (without this revision) `test.a` is still not on the worklist.

Note: In the above example, an `OpRewritePattern<OpB>` could have been used instead of an `OpRewritePattern<OpA>`. With such a design, we can run into the same problem (when the `eligible` attr is on `test.a` and `test.b` is removed from the worklist because no patterns could be applied).

Note: This change uncovered an unrelated bug in TestSCFUtils.cpp that was triggered due to a change in the order in which ops are processed. A TODO is added to the broken code and test cases are adapted so that the bug is no longer triggered.

[MemDep] Reduce block limit

The non-local MemDep analysis has a limit on the number of blocks
it will scan trying to find dependencies. The current limit of 1000
is very high, especially when we consider that each block scan can
also visit up to 100 instructions. In degenerate cases (where we
actually scan that many blocks) MemDep/GVN dominate overall
compile-time, for little benefit.

This patch reduces the limit to 200, which is probably still too
large, but at least mitigates some of the more catastrophic cases.
(For comparison, MSSA clobber walks consider up to 100
MemoryDefs/MemoryPhis, rather than 200 blocks * 100 instructions,
but these limits aren't directly comparable.)

I know that we were kind of hoping that this issue would resolve
itself in time, either by a switch to NewGVN or use of MSSA in GVN.
But I think we should still address this in the meantime.
Additionally, a switch to an MSSA-based implementation will
effectively be doing this as well, in a roundabout way (by dint of
MSSA having lower cutoffs than MDA).

[flang] Lower elemental intrinsics to hlfir.elemental

- Move the core code generating hlfir.elemental for user calls from
  genUserElementalCall into a new ElementalCallBuilder class and use
  C++ CRTP (curiously recursive template pattern) to implement the
  parts specific to user and intrinsic call into ElementalUserCallBuilder
  and ElementalIntrinsicCallBuilder. This allows sharing the core logic
  to lower elemental procedures for both user defined and intrinsics
  procedures.

- To allow using ElementalCallBuilder, split the intrinsic lowering code
  into two parts: first lower the arguments to hlfir::Entity regardless
  of the interface of the intrinsics, and then, in a different function
  (genIntrinsicProcRefCore), prepare the hlfir::Entity according to the
  interface. This allows using the same core logic to prepare "normal"
  arguments for non-elemental intrinsics, and to prepare the elements of
  array arguments inside elemental call (ElementalIntrinsicCallBuilder
  calls genIntrinsicProcRefCore once it has computed the scalar actual
  arguments).
  To allow this split, genExprBox/genExprAddr/genExprValue logic had to
  be split in ConvertExprToHlfir.[cpp/h].

- Add missing statement context pushScope/finalizeAndPop around the
  code generation inside the hlfir.elemental so that any temps created
  while lowering the call at the element level is correctly cleaned-up.

- One piece of code in hlfir::Entity::hasNonDefaultLowerBounds() was wrong for assumed shape arrays (returned true when an assumed shaped array had no explicit lower bounds). This caused the added test to hit a bogus TODO, so fix it.

[lldb/crashlog] Refactor CrashLogParser into a Factory pattern

This patch should fix an undefined behaviour that's happening when
parsing a crash report from an IDE. In the previous implementation, the
CrashLogParser base class would use the `__new__` static class method to
create the right parser instance depending on the crash report type.

For some reasons, the derived parser initializer wouldn't be called when
running the command from an IDE, so this patch refactors the
CrashLogParser code to replace the use of the `__new__` method with a
factory `create` static method.

`-object_path_lto` now sets `c.AlwaysEmitRegularLTOObj` as in the other ports,
