If a precompiled package's init function tries to itself require that
package (e.g. by importing a symbol from a submodule of that package),
we would run into a deadlock. Fix that by delaying the running of
initializers until after we've had a chance to register any root module.

Pointers can have different types. For these, a simple bitcast
suffices rather than going through inttoptr.

Most of the support was already there, but it was mostly unexercised.
The recent activation of the SLP vectorizer made these patterns appear

The legality check was using use counts after `finish(compact)` got
to delete, which made them inaccurate. Instead, take a copy of the
use counts before. Additionally, ignore any uses that got deleted
during `finish(compact)`. Fixes #28444.

Adding `-fno-asynchronous-unwind-tables` to the C compiler flags passed
to OpenBLAS works around errors claiming an invalid register for
`.seh_savexmm`. We've been running into this on the 64-bit Windows
buildbots.

See discussion in OpenMathLib/OpenBLAS#1708.
