I do not want compiler attributes like __clang__ or __linux__ scattered
everywhere to detect the platform Ballistic is running on, so I added
preprocessor directives to make things a lot cleaner.

Also remove bal_translate_block() body. It will need to be redesigned
to be used by bal_engine_run().

Instead of using strcmp() on each decoded intruction's mnemonic to
translate it, we embedd an IR opcode into the struct. This is a very
barebones implementation and does not cover the entire ARM instruction
set. ARM instructions that does not have an IR opcode equivalent will be
marked with `OPCODE_TRAP` and should be implemented in the future.

At first I wondered how will we know the bitfield of the ssa variable
we're creating? Should we hardcode the bit width in the opcode and
create a large switch statement or hash table? To keep things simple
I just added a new bit width parameter to emit_instruction() and it
will be the frontend's responsibility to find the correct bitwidth.
This should better for x86 lowering.

The decoder API is now suitable to be made public. decoder.h is the sole
entry point for the decoder and it has been moved to `include/`
