308ba80597 fix(cc): make link and preprocessor logic to be more consistent with 
clang's behavior.

1. `zig cc main.c -o /dev/null` shouldn't emit a.out
2. `zig cc -E main.c` and `zig cc -E main -o -` should output to stdout

71d16106ad Sema: @memcpy changes 
* The langspec definition of `@memcpy` has been changed so that the
  source and destination element types must be in-memory coercible,
  allowing all such calls to be raw copying operations, not actually
  applying any coercions.
* Implement aliasing check for comptime `@memcpy`; a compile error will
  now be emitted if the arguments alias.
* Implement more efficient comptime `@memcpy` by loading and storing a
  whole array at once, similar to how `@memset` is implemented.

aa37a5a0c4 zig.h: Add some casts to __atomic macros to shut Clang warnings up. 
This is a stupid Clang-ism:

    ❯ cat test.c
    int main() {
        int value = 42;
        int const *value_ptr = &value;
        int location;
        __atomic_store(&location, value_ptr, __ATOMIC_SEQ_CST);
    }
    ❯ gcc test.c -fsyntax-only
    ❯ clang test.c -fsyntax-only
    test.c:5:31: warning: passing 'const int *' to parameter of type 'int *' discards qualifiers [-Wincompatible-pointer-types-discards-qualifiers]
        5 |     __atomic_store(&location, value_ptr, __ATOMIC_SEQ_CST);
          |                               ^~~~~~~~~
    1 warning generated.

I have no idea why Clang doesn't define these builtins as taking const pointers
for the parameters that are only read from. Anyway, after the next zig1.wasm
update, this change should shut up these warnings that we've been seeing in CI
during bootstrap for ages.

df1fa36feb Revert "std.http.Server: add Request.getHeader() function (#21625)" 
This reverts commit 21823d1b5d1ebfa27df954c2cef5d0f231fb8402.

It's a bad API that could easily lead to O(N^2) logic.

Turns out this was already fixed in #21964.

I have no idea why GitHub showed an incorrect diff in #21273, or how applying the diff to master was even possible, but here we are.

compiler: Rework LTO settings for some Zig-provided libraries. 
* compiler-rt and mingw32 have both run into LLD bugs, and LLVM disables LTO for
  its compiler-rt, so disable LTO for these.
* While we haven't run into any bugs in it, LLVM disables LTO for its libtsan,
  so follow suit just to be safe.
* Allow LTO for libfuzzer as LLVM does.

link: Set machine and float ABI when invoking ld.lld and lld-link. 
If this isn't done, LTO can completely miscompile the input bitcode modules for
certain targets where we need to explicitly set these ABIs (because LLVM's
defaults are bad).
