* it is now -fcompiler-rt and -fno-compiler-rt to override the (quite
reasonable) default of bundling compiler-rt only for executables and
dynamic libraries.
- the build.zig API is still called bundle_compiler_rt however it is
now an optional bool instead of a bool. leaving it as `null` means
to use the compiler default.
* renamed some internal identifiers to make the source more readable
* additionally support -fcompiler-rt when doing build-obj for ELF files
since that target already supports linking multiple objects into one.
- includes an error message when attempting this for non-ELF. in the
future this could additionally be supported with a more advanced
implementation that does not rely on the linker.
* properly populate the linker cache hash
I spent a long time working on this data structure, and I still think
it's a neat idea, but it has no business being in the std lib.
I'm aware of the few remaining references to SegmentedList that exist in
the std lib, but they are dead code, and so I'm leaving the dead
references as a clue that the code is dead. Cleaning up dead code will
be a separate effort that involves code coverage tools to make sure we
find it all.

stderr_mutex may still be held when we reach the signal handler, grab
our own stderr handle to print the error messages and avoid deadlocking.
Closes#7247
fork() on Linux/sparc64 seems to return its result in two registers,
with %o0 always holding the current process' PID, and the parent/child
status returned in %o1. Add some glue code to convert those into
the libc-style return value.
* always align the stack to 16. I saw an instance on x86_64 linux where
it was needed.
* detect at runtime if being interpreted by a dynamic loader and if so
avoid clobbering the fs register.
Find the effective ELF load address in dl_iterate_phdr by computing the
difference between the in-memory phdr and its p_vaddr specified in the
ELF file.
This makes the dl_iterate_phdr test pass and restores the stack traces.

Will manually apply the diffs to these deleted files to the new zig
code in a followup commit.
The previous clone() definition was written for 32bit PPC targets,
trying to execute it on a PPC64 machine lead to countless crashes.
Use the clone() definition kindly lifted from Musl libc.
