swift_slowAlloc() assumes malloc(0) returns non-NULL. (#86922 )
...
`swift_slowAlloc()` and related functions assume that `malloc(0)` and `aligned_alloc(0)` return non-`NULL` pointers. The C standards allow implementations to return `NULL` when the allocation size is `0`.
This PR implements a check for `0` that instead allocates `1`. The cost of the check is negligible next to the cost of actually allocating, but we'll mark it `SWIFT_UNLIKELY` just in case.

Optimizer: let OSSA canonicalization always respect deinit barriers
...
When computing the region to search for deinit barriers, include _all_ destroys of a canonical liverange - including destroys of all copies.
Before this fix, only destroys of the original def were considered which resulted in moving destroys across deinit barriers.

FP Parsing: Fix over-eager underflow check

An early check for underflow was a bit too aggressive, resulting in values that
would otherwise round up to the smallest subnormal failing to go through the
regular rounding logic.

Fix parsing issues on 32-bit hosts
...
These were mostly bugs with code of the following form:
```
if uint64Value < (... literal expression ...)
```
Swift's comparison operators allow their left- and right-hand sides to be of
different widths. This in turn means that the literal expression above
typically gets typechecked by default as a plain `Int` or `UInt` expression.
In a number of cases, this led to truncation on platforms where `Int` is
not 64 bits.
In particular, this seems to fix tests on wasm32.
