These are the last PowerPC cross targets that still use the IBM 128-bit long
double format. I'm not convinced anyone cares enough about them to justify
keeping them around, so this drops support. powerpc-linux-musleabi(hf), which
use the IEEE format, are still fully supported for people who want to use old
32-bit PowerPC hardware.
setKey used to just call rebuildIndex which allocates a new index and
inserts into it all entries. This is the only allocation that setKey
needed to do.
Instead I propose that setKey sets the key in the entries and then does
a remove of the old key from the index and insert of the new key into
the index. This eliminates the need for setKey to allocate and makes
it infallible
To achieve this I extracted a helper function for inserting a single
entry into the index. Function for removing one entry from the index
already exists. setKey now just calls these two functions.
Since `packed` containers are now internally represented by a `bitpack`,
they need special handling on initialization: they need to be either
bitpacked or bitcasted to their backing integer. `Sema` already did this,
but `LowerZon` didn't yet.
`HINSTANCE` is `*opaque {}` so using a type that should be compatible from alternate bindings (zigwin32, for example) would be a (false positive) compile error without this ptrCast.
Largely mirrors Haiku, Serenity provides crt0 and GCC the rest (though
only crtbegin/crtend are used as per serenity's toolchain patches[1]):

Serenity has a GCC and LLVM toolchain that work equally well, support
for the latter may be added in the future.

This PR merges the functionality of the `getLastOrNull` method into `getLast`, which improves consistency as its
based on methods like `front`, `back`, and `peek` in the `Deque` and `PriorityQueue` containers.

Because this syntax is not heavily used, and the migration can be done
with a simple text substitution, I do not believe a `zig fmt` fixup is
necessary for this change.
