Utils

• Add ReflectionHelper.IsMono and IsCore, check for Mono.RuntimeStructs (modern mono).
• Make DynDll act as a shim for NativeLibrary on .NET Core.
• Fix reflection cache fixer on .NET Framework 3.5.

RuntimeDetour

• Implement initial precode walking for arm64 (Thanks, @kevzhao2!).
• Fix compatibility with Windows x86 .NET 6.0 (x64 worked fine).
  • ICorJitCompiler compileMethod switched from StdCall to ThisCall for this specific version of the .NET runtime despite no changes to the function definition, presumably due to minor compile-time differences.

RuntimeDetour

• Check for and use the new RuntimeHelpers.CompileMethod(RuntimeMethodHandleInternal) signature found in .NET 5 and newer.
  • This works around the first chance exception handler deadlock triggered by tModLoader. Here's a general reminder to not call methods which could be in process of being detoured.

Utils

• Fix Android support by bypassing SELinux for platform check (Thanks, @MeWnoJinsei!).
• Fix busybox on Windows messing with platform check.
• Fix ILPatternMatchingExt.Match<T>(Instruction, OpCode, out T) (always returned false).
• Add callvirt get_Assembly (Mono vs .NET) fix for DMDEmit as well (Thanks, @ghorsington!).

RuntimeDetour

• Check if dynamic IL is available in TryMemAllocScratchCloseTo, fixing problems in some Unity environments.

Patcher

• Fix generic parameters not being cloned / relinked properly (Thanks, @Popax21!).
• Fix Mono weirdness regarding custom attribute constructor references (must be method ref + type ref, or method def, not method ref + type def) (Thanks, @Popax21!).

RuntimeDetour

• Even more struct-related fixes.

RuntimeDetour

• On .NET Framework 4.8 x86, trunks can be chained just as with Core x64. This should fix a very occasional ExecutionEngineException edge case in a limited amount of projects.

RuntimeDetour

• Add the .NET 6.0 JIT GUID: there don't seem to be any breaking changes between .NET 5.0 and 6.0 so far.
