The purposes of this attribute is to let procedures opt-out of being
instrumented with asan. Typically an allocator that includes 'in-band'
meta-data will be accessing poisoned values (such as tlsf).
Making asan work with these allocators becomes very challenging so
just being to ignore asan within specific allocator procedures
makes it easier to reason and removes the need to temporarily
poison and unpoison allocator data.
This vet flag will make it so that allocators must be explicitly used
in places where context.allocator and context.temp_allocator are a
procedure parameter.
The goal of this flag is to prevent using the context.allocator in
cases where a different allocator was meant to be used.
Some code bases default context.allocator to nil/panic allocator
to catch this at runtime. This effectively makes it a compile
time error instead.
allocators
This adds various bindings to the asan runtime which can be used
to poison/unpoison memory handed out by various allocators. This
means we can catch use after free memory bugs when using operations
such as free_all during runtime.
Asan poisoning are added for the follow allocators in mem:
Arena (including temporary arenas)
Scratch
Stack
Small_Stack
Additionally a bug in the stack allocator was fixed to disallow freeing
in the middle of the stack (caught by the asan!).
I plan on adding support for all the allocators in core. This is just
a good starting point and were some of the easiest ones to implement
asan for.
Do not memory map files; Windows cannot write to a file that is memory

Write cache after llvm building. This ensures the cache won't have a
false positive if llvm fails.

* Use new 'Returns:' and 'Inputs:' keywords used by the website generator
* Make order item order resemble website, i.e. 'Returns:' comes before
'Example:'
* Add a few missing input items
* Add a few missing return items
* Strings will respect widths smaller than the string's length
* Strings are right justified by default like integers
* Strings accept '-' flag to be left justified
* Booleans will be formatted like strings
* Enums will be formatted like strings
