[GuardWidening] Choose right point for generating wide condition for branches. PR60234
When guards are represented as widenable branches, there is a tricky
situation when the branch stays in loop but widenable condition doesn't.
It means that the widenable condition is loop-invariant, and some other
optimizations could have done changes using this fact.
If widening is allowed to create widened condition inside this loop,
and join the loop-invariant wc with some non-invariant facts, it can
cause miscompile. See example of this at https://github.com/llvm/llvm-project/issues/60234.
The solution is to adjust the point of generationg the wide condition,
and therefore of hoisting all related parts there. It should not be before
the branch, but before the widenable_condition call. The fact that `wc()`
and the wide condition are in the same block guarantees that they will
not violate the invariance property for any loop.

[mem2reg][debuginfo] Handle op_deref when converting dbg.declare
The conversion of dbg.declare into dbg.values doesn't take into account
the DIExpression attached to the intrinsic. In particular, when
converting:
```
store %val, ptr %alloca
dbg.declare(ptr %alloca, !SomeVar, !DIExpression())
```
Mem2Reg will try to figure out if `%val` has the size of `!SomeVar`. If
it does, then a non-undef dbg.value is inserted:
```
dbg.value(%val, !SomeVar, !DIExpression())
```
This makes sense: the alloca is _the_ address of the variable. So a
store to the alloca is a store to the variable. However, if the
expression in the original intrinsic is a `DW_OP_deref`, this logic is
not applicable:
```
store ptr %val, ptr %alloca
dbg.declare(ptr %alloca, !SomeVar, !DIExpression(DW_OP_deref))
```
Here, the alloca is *not* the address of the variable. A store to the
alloca is *not* a store to the variable. As such, querying whether
`%val` has the same size as `!SomeVar` is meaningless.
This patch addresses the issue by:
1. Allowing the conversion when the expression is _only_ a `DW_OP_deref`
without any other expressions (see code comment).
2. Checking that the expression does not start with a `DW_OP_deref`
before applying the logic that checks whether the value being stored and
the variable have the same length.

It closely follows the design of the TBAA metadata import with an

only one module-level metadata operation for all kinds of metadata.
This design ensures there is only one metadata operation that pollutes
the user namespace.
The import of loop metadata, which will use the access groups,
is left to a follow up revision.
