Major release! 🥂

Starting with this version, the toolchain is now based on LLVM, an open-source retargetable compiler infrastructure. The backend was created by Jacobly and the compiler (named clang, which you may see as ez80-clang in the toolchain) is now able produce eZ80 assembly from C/C++ source files. This is a major milestone as it allows the CE toolchain to move away from using the legacy Zilog ZDS compiler, which is closed-source, proprietary, only worked on Windows, and contained numerous bugs. Thanks to LLVM, later standards of the C and C++ specifications are supported (you're not stuck with C89 anymore!), code optimization actually works, and the compiler is able to run natively across multiple platforms.

• Lots of cleanup and improvements to the standard includes and headers in general, made possible by the compiler change mentioned above.
• Various changes and improvements to the fasmg linker (written by Jacobly as well)
• Some "hacks" like _OS and _asm aren't needed anymore, they are now gone.
• Debug info is now produced in the Dwarf format (and source-level debugging support within CEmu is getting closer to being ready!)
• The convimg project has been updated to support a new YAML format that is easier for beginners and tooling. The previous toolchain release (v8.8) also used a YAML format, however some slight modifications were made in order to make it standard-compliant. Example convimg.yaml conversion files can be found in the examples.
• New fileioc function: ti_SetGCBehavior to set routines to run before and after a garbage collect would be triggered.
• New keypadc defines: many keypad key defines corresponding to the TI-83 Premium CE keypad were added for easier coding
• New usb.h function: usb_BatteryCharging to check if the battery is currently charging.
• New time.h headers and functions: standard features. See commit for details.
• New tice.h defines and macros: easier ways to control timers. See commit for details.
• Revamped v/s/printf functions, now available if needed thanks to a light third-party library, see docs.
• New C++ header-only "library" for easily manipulating "TI real" numbers (see this PR), making some math operations easier. See examples.
• abort() doesn't generate code that would make CEmu open its debugger anymore - you can use the specific debug functions for that now.
• Various optimizations in library functions
• Various makefile improvements and cleanup (bugfixes, portability...)
• Improved autotests for the examples
• fasmg got a speed boost thanks to CALM instructions.
• Documentation improved and revamped. Available on online here, which replaces the repo's wiki
• The build/CI infrastructure was migrated from Travis to Github Actions.

These massive internal changes do mean that some programs might not compile right away anymore, but don't worry, it shouldn't be too difficult to fix your code. Check out the v9.0 release note for migration tips.
