std.debug: prefer FP unwinding on targets where it is ideal
...
If the ABI requires a backchain pointer, FP unwinding is always possible, safe,
and fast, so there's really no reason not to use it.

The previous version (ported from musl) used bit-by-bit calculations and was slow, but the current version (also ported from musl) uses lookup tables combined with Goldschmidt iterations to significantly improve the speed.

drop support for powerpc64 ELF v1
...
* ELF v1 on powerpc64 is only barely kept on life support in a couple of Linux
distros. I don't anticipate that this will last much longer.
* Most of the Linux world has moved to powerpc64le which requires ELF v2.
* Some Linux distros have even started supporting powerpc64 with ELF v2.
* The BSD world has long since moved to ELF v2.
* We have no actual linking support for ELF v1.
* ELF v1 had confused DWARF register mappings which is becoming a problem in
our DWARF code in std.debug.
It's clear that ELF v1 is on its way out, and we never fully supported it
anyway. So let's not waste any time or energy on it going forward.

std.zig.system: add OS checks for QEMU in getExternalExecutor()
...
FreeBSD doesn't support the same number of platforms as Linux, and even then,
only has usermode emulation for a subset of its supported platforms.
NetBSD's usermode emulation support is apparently just broken at the moment.

For the supported COFF machine types of X64 (x86_64), I386 (x86), ARMNT (thumb), and ARM64 (aarch64), this new Zig implementation results in byte-for-byte identical .lib files when compared to the previous LLVM-backed implementation.
