4fc783670a Sema/arith.zig: Fixing more typos from #23177. 
This is a complementary PR to #23487 (I had only found one typo before).

Now I've looked at the whole `arith.zig` file, trying to find other potential problems.

Make translate-c more robust in handling macro functions. 
Translate-c didn't properly account for C macro functions having parameter names that are C keywords. So something like `#define FOO(float) ((float) + 10)` would've been interpreted as casting `+10` to a `float` type, instead of adding `10` to the parameter `float`.

An example of a real-world macro function like this is SDL3's `SDL_DEFINE_AUDIO_FORMAT` from `SDL_audio.h`, which uses `signed` as a parameter.

Sema: Prevent tail calls of std.builtin.returnError(). 
LLVM 20 started tail-calling it in some of our test cases, resulting in:

instead of the expected:

libcxx: Update to Clang 20. 
See:

* https://discourse.llvm.org/t/rfc-freezing-c-03-headers-in-libc/77319
* https://discourse.llvm.org/t/rfc-project-hand-in-hand-llvm-libc-libc-code-sharing/77701

We're dropping support for C++03 for Zig due to the first change; it would be
insane to ship 1018 duplicate header files just for this outdated use case.

As a result of the second change, I had to bring in a subset of the headers from
llvm-libc since libc++ now depends on these. Hopefully we can continue to get
away with not copying the entirety of llvm-libc.

translate-c: fix function prototype decalared inside a function 
* If a function prototype is declarated inside a function, do not
  translate it to a top-level extern function declaration. Similar to
  extern local variable, just wrapped it into a block-local struct.

* Add a new extern_local_fn tag of aro_translate_c node for present
  extern local function declaration.

* When a function body has a C function prototype declaration, it adds
  an extern local function declaration. Subsequent function references
  will look for this function declaration.

Zcu: fix ZOIR cache bugs 
* When saving bigint limbs, we gave the iovec the wrong length, meaning
  bigint data (and the following string and compile error data) was corrupted.
* When updating a stale ZOIR cache, we failed to truncate the file, so
  just wrote more bytes onto the end of the stale cache.

d53cc5e5b2 Sema: allow @ptrCast slice of zero-bit type to slice of non-zero-bit type 
This is actually completely well-defined. The resulting slice always has
0 elements. The only disallowed case is casting *to* a slice of a
zero-bit type, because in that case, you cna't figure out how many
destination elements to use (and there's *no* valid destination length
if the source slice corresponds to more than 0 bits).
