zig ld: handle -V linker arg 
The "-V' argument lists the supported emulations. While linker
emulation is not implemented, it's beneficial to warn user regarding
this.

f1af53f68e macho: use pread syscall when loading tapi file 
This avoids mixing preads with reads which do not mix well especially
on Windows.

54b7e144b1 initial support for integrated fuzzing 
* Add the `-ffuzz` and `-fno-fuzz` CLI arguments.
* Detect fuzz testing flags from zig cc.
* Set the correct clang flags when fuzz testing is requested. It can be
  combined with TSAN and UBSAN.
* Compilation: build fuzzer library when needed which is currently an
  empty zig file.
* Add optforfuzzing to every function in the llvm backend for modules
  that have requested fuzzing.
* In ZigLLVMTargetMachineEmitToFile, add the optimization passes for
  sanitizer coverage.
* std.mem.eql uses a naive implementation optimized for fuzzing when
  builtin.fuzz is true.

std.Target.Os: Rename lv2 to ps3. 
It is very non-obvious that this is what lv2 refers to, and we already use ps4
and ps5 to refer to the later models, so let's just be consistent.

std.Target: Remove the tce/tcele arch tags. 
There is no obvious reason why this would be relevant for Zig to target. I
rather question the value of LLVM even having target triple code for this, too.

std.Target: Remove the shave arch tag. 
This was added as an architecture to LLVM's target triple parser and the Clang
driver in 2015. No backend ever materialized as far as I can see (same for GCC).
In 2016, other code referring to it started using "Myriad" instead. Ultimately,
all code related to it that isn't in the target triple parser was removed. It
seems to be a real product, just... literally no one seems to know anything
about the ISA. I figure after almost a decade with no public ISA documentation
to speak of, and no LLVM backend to reference, it's probably safe to assume that
we're not going to learn much about this ISA, making it useless for Zig.

std.Target: Remove amdil/amdil64 arch tags. 
This is really obscure and no one is 100% sure what it is. It seems to be old
and unused. My suspicion is that it's just an old term for "AMDGPU" before it
was upstreamed to LLVM.

std.Target: Remove the r600 arch tag. 
These are quite old GPUs, and it is unlikely that Zig will ever be able to
target them.

std.posix: Consider invalid signal numbers to sigaction() to be programmer error. 
The set of signals that cannot have their action changed is documented in POSIX,
and any additional, non-standard signals are documented by the specific OS. I
see no valid reason why EINVAL should be considered an unpredictable error here.
