- Mangles (T0, T1) as tuple<T0, T1>, possibly unblocking rust-lang#70052 "Update hashbrown to 0.8.0" - Prettifies Rust tuples similar to VS2017's std::tuple - Improves debuginfo test coverage

PDB debug information doesn't appear to be emitted for basic types. By defining u32 as a typedef for unsigned __int32 when targeting MSVC, we allow CDB and other debuggers to recognize "u32" as a type/expression. This in turn unblocks rust-lang#70052 "Update hashbrown to 0.8.0" by allowing $T1 ..= $T3 to resolve, which would otherwise fail to resolve when builtin types fail to parse.

When cross-compiling, the LLVM build system recurses to build tools that need to run on the host system. However, since we pass cmake defines to set the compiler and target, LLVM still compiles these tools for the target system, rather than the host. The tools then fail to execute during the LLVM build. This change sets defines for the tools that need to run on the host (llvm-nm, llvm-tablegen, and llvm-config), so that the LLVM build does not attempt to build them, and instead relies on the tools already built. If compiling with clang-cl, this change also adds the `--target` option to specify the target triple. MSVC compilers do not require this, since there is a separate compiler binary for cross-compilation.

As of rust-lang#73564, the --eh-frame-hdr flag is unconditionally passed to linkers on many platforms. The illumos link editor does not currently support this flag. The linker machinery in the Rust toolchain currently seems to use the (potentially cross-compiled) target to choose linker flags, rather than looking at what might be running on the build system. Disabling the flag for all illumos/Solaris targets seems like the best we can do for now without more serious surgery.

By making the proc macro abort if any symbols are out of order. The commit also changes the proc macro collect multiple errors (of order or duplicated symbols) and prints them at the end, which is useful if you have multiple errors.

Because it represents the symbol `ItemContext`, and `sym` identifiers are supposed to match the actual symbol whenever possible.

Use `matches!` instead of old `if let`

This to fix rust-lang#74081.

…manieu debuginfo: Mangle tuples to be natvis friendly, typedef basic types These changes are meant to unblock rust-lang#70052 "Update hashbrown to 0.8.0" by allowing the use of `tuple<u64, u64>` as a .natvis expression in MSVC style debuggers (MSVC, WinDbg, CDB, etc.) * f8eb81b does the actual mangling of `(u64, u64)` -> `tuple<u64, 64>` * 24a728a allows `u64` to resolve (fixing `$T1` / `$T2` when used to visualize `HashMap<u64, u64, ...>`)

Rename sym::item_context as sym::ItemContext.

714b6ec

Because it represents the symbol `ItemContext`, and `sym` identifiers are supposed to match the actual symbol whenever possible.
