* Check for overflow when calculating the slice start & end position.
* Align the pointer obtained from the allocator, ensuring that it
  satisfies user requested alignment (the allocator is only asked for
  layout compatible with u8 slice).
* Remove an incorrect assertion from DroplessArena::align.

Return a pointer from `alloc_raw` instead of a slice. There is no
practical use for slice as a return type and changing it to a pointer
avoids forming references to an uninitialized memory.

Apparently it got changed.

Check for overflow in DroplessArena and align returned memory

* Check for overflow when calculating the slice start & end position.
* Align the pointer obtained from the allocator, ensuring that it
  satisfies user requested alignment (the allocator is only asked for
  layout compatible with u8 slice).
* Remove an incorrect assertion from DroplessArena::align.
* Avoid forming references to an uninitialized memory in DroplessArena.

Helps with rust-lang#73007, rust-lang#72624.

Don't run generator transform when there's a TyErr

Not sure if this might cause any problems later on, but we shouldn't be hitting codegen or const eval for the produced MIR anyways, so it should be fine.

…tions, r=kinnison

Re-order correctly the sections in the sidebar

Before that, "trait implementations" and "implementors" titles in the sidebar were before "methods" for example. Which wasn't logical considering that the two sections come after in the "content".
