6f3767862d implement std.testing.fuzzInput 
For now this returns a dummy fuzz input.

5058beb179 implement std.testing.fuzzInput 
for the -fno-fuzz case. The other case will take more work in libfuzzer.

1c35e73b61 llvm: Don't emit safety memset() for stores of undef in Debug with safety off. 
Before, this code:

    @setRuntimeSafety(false);
    var arr: [38]elf.Addr = undefined;

would emit a call to memset() in the output code in Debug mode, while in all the
release modes, LLVM optimized the memset() out as expected. Emitting the call in
Debug mode is problematic in some contexts, e.g. in std.os.linux.start_pie where
we are not yet ready to correctly perform calls because relocations haven't been
applied yet, or in the early stages of a dynamic linker, etc.

5478b0eb38
start: Simplify mips and mips64 startup code. 
Switches from using r1 as a temporary to r2. That way, we don't have to set the
`noat` assembler option. (r1 is the scratch register used by the assembler's
pseudoinstructions; the assembler warns when code uses that register explicitly
without `noat` set.)

f4f5b2bc41 llvm: force TargetOptions.UseInitArray to true 
The `TargetOptions` default constructor initializes all `bool`s to
`false`, yet clang defaults to setting this option to `true`.  Since
recent glibc versions on linux do not appear to support this being set
to `false`, just changing the default for now unless a use case for
making it configurable is found.

1e74904aa2 Replace some dynamic functions with static ones. 
PR [19271](https://github.com/ziglang/zig/pull/19271) added some static function implementations from kernel32, but some parts of the library still used the dynamically loaded versions.

26d2a7960e default "trace pc guard" coverage off 
* Add -f(no-)sanitize-coverage-trace-pc-guard CLI flag which defaults to
  off. This value lowers to TracePCGuard = true (LLVM backend) and -Xclang
  -fsanitize-coverage-trace-pc-guard. These settings are not
  automatically included with -ffuzz.
* Add `Build.Step.Compile` flag for sanitize_coverage_trace_pc_guard
  with appropriate documentation.
* Add `zig cc` integration for the respective flags.
* Avoid crashing in ELF linker code when -ffuzz -femit-llvm-ir used
  together.

33d4742456 LLVM: more fine-grained sancov emit options 
Exposes sanitizer coverage flags to the target machine emit function.
Makes it easier to change sancov options without rebuilding the C++
files.

This also enables PCTable = true for sancov which is needed by AFL, and
adds the corresponding Clang flag.
