* sysident_assym.h was manually expanded.
* The ELF_NOTE_MARCH_DESC and ELF_NOTE_MARCH_DESCSZ macros will be defined
by the compiler.
* Legacy .init/.fini stuff was removed.
* GCJ nonsense was removed.
Error messages never contain periods or grave accents.
Get rid of the periods and use apostrophes instead in
probably the only two error messages that had them.
* ucontext_t ptr is 8-byte aligned instead of 16-byte aligned which @alignCast() expects
* Retrieve pc address from ucontext_t since unwind_state is null
* Work around __mcontext_data being written incorrectly by the kernel
Textual PTX is just assembly language like any other. And if we do ever add
support for emitting PTX object files after reverse engineering the bytecode
format, we'd be emitting ELF files like the CUDA toolchain. So there's really no
need for a special ObjectFormat tag here, nor linker code that treats it as a
distinct format.
* NT_FREEBSD_ABI_TAG was manually adjusted from using a hardcoded value to using
__FreeBSD_version which will be defined by the compiler.
* GCJ stuff was removed.
* HAVE_CTORS definitions were removed.
* Introduce common `bzero` libc implementation.
* Update test name according to review

* address code review
- import common implementation when musl or wasi is included
- don't use `c_builtins`, use `@memset`
* bzero calling conv to .c
* Apply review

For C code the macros SIGRTMIN and SIGRTMAX provide these values. In
practice what looks like a constant is actually provided by a libc call.
So the Zig implementations are explicitly function calls.
glibc (and Musl) export a run-time minimum "real-time" signal number,
based on how many signals are reserved for internal implementation details
(generally threading). In practice, on Linux, sigrtmin() is 35 on glibc
with the older LinuxThread and 34 with the newer NPTL-based
implementation. Musl always returns 35. The maximum "real-time" signal
number is NSIG - 1 (64 on most Linux kernels, but 128 on MIPS).
When not linking a C Library, Zig can report the full range of "rt"
signals (none are reserved by Zig).
