start: Align the stack on sparc64 just in case. 
The kernel does this as required, but we cannot trust dynamic linkers to do it.

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.)

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.

Merge pull request #20706 from alexrp/sigaction-nosys

e8503ecb65 Default std.posix.system.ucontext_t is void 
PR https://github.com/ziglang/zig/pull/20679 ("std.c reorganization")
switched feature-detection code to use "T != void" checks in place of
"@hasDecl".  However, the std.posix.system struct is empty, so
compile-time feature detection against symbols in there (specifically
`std.posix.system.ucontext_t` in this case), fail at compile time on
freestanding targets.

This PR adds a void ucontext_t into the std.posix.system default.

This PR also adds pseudo-"freestanding" variation of the StackIterator
"unwind" test.  It is sort of hacky (its freestanding, but assumes it can
invoke a Linux exit syscall), but it does detect this problem.

Fixes #20710

bde8c4a46a update start code to use @disableInstrumentation 
This prevents it from trying to access thread local storage before it
has set up thread local storage, particularly when code coverage
instrumentation is enabled.

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.
