Sækja Odin Programming Language dev-2024-07

New Language Features
- Allow for constant strings in `foreign import`s
- `#exists(<string>) -> bool`
- `@(rodata)`
- `context.random_generator`
- Brand new `runtime.Random_Generator` interface

Compiler Improvements
- Brand new Multithreaded Test Runner
- https://github.com/odin-lang/Odin/pull/3646
- Improvements to error line rendering
- Full support for Unicode grapheme clusters
- NetBSD ARM64 support
- `-show-defineables` and `-export-defineables`
- `-vet-cast`
- Looks for redundant `casts` or `transmute`s, and `transmute`s that should be `cast`s
- `-strict-style` now enforces a lot more regarding the official Odin code base style
- `-vet-style` is a much weaker form that does not have all of the same enforced options as `-strict-style`
- Enforces `-vet-cast`
- Enforces `case` statements to be in the same column as their `switch` token
- Enforces 1TBS style
- `-vet-tabs`
- Enforces tabs to be used for indentation with statements/declarations
- `-custom-attribute:<string>`
- `-custom-attribute:attr1`
- `-custom-attribute:attr1,attr2`
- `-custom-attribute:attr1 -custom-attribute:attr2`
- Improve parsing for `label: #reverse for` and `label: #partial switch`
- Allow `#soa` arrays to be used directly with `make`, `reserve`, `append`, etc.
- `intrinsics.procedure_of(call(...))`
- `intrinsics.syscall_bsd`
- Fixes to debug information generation for LLVM < 13
- Add `#directory` (complements `#file`)
- Remove `@(warning)` and `#warning`
- Allow `- constant_array`
- Support `@(extra_linker_flags)` on WASM targets
- Use `f32` operations when doing `complex32` and `quaternion64` operations to improve accuracy and performance
- Allow for `when x in y {` (minor oversight in syntax)
- Keep `bit_field` accesses happy with `-santitize:address`
- Fix for `bit_set[$T]` not setting the bounds correctly (https://github.com/odin-lang/Odin/pull/3842)
- `intrinsics.type_struct_has_implicit_padding`
- Remove quite a few possible race conditions in the compiler
- Numerous big fixes
