Crux v0.8

New features

• [LLVM] Add support for LLVM bitcode files produced by Apple Clang on macOS.
• [LLVM] Implement overrides for the LLVM llvm.is.fpclass.f* intrinsics.
• [LLVM] Implement overrides for the isinf, __isinf, and __isinff C functions.
• [LLVM] Implement overrides for the LLVM llvm.fma.f* and llvm.fmuladd.f* intrinsics.
• [LLVM] Implement overrides for the fma and fmaf C functions.
• [MIR] Support the nightly-2023-01-23 Rust toolchain. Some of the highlights of this include:
  • Properly support for Rust's new constant forms
  • Better support for zero-sized constants
  • Encoding enum discriminant types so that crux-mir can know about non-isize discriminant types (e.g., Ordering, which uses an i8 discriminant)
  • A more intelligent way of computing crate disambiguators for looking up known types such as MaybeUninit and Option
• [MIR] Support enums marked with repr(transparent).
