Simplify the raise instruction to reduce code size
The raise/2 instruction is almost always used like this: raise x(2) x(1) Therefore, we can translate it to an internal i_raise/0 instruction that uses x(2) x(1) as its implicit operands. We will also remove the backward compatibility with R10-0. It is unlikely that anyone still is using BEAM files compiled with the R10-0 compiler, especially since most of those modules cannot be loaded. The loader will refuse to load any module that uses the old non-GCIng arithmetic instructions or the non-GCing versions of length/1 or size/1. Doing these changes will reduce both the size of the loaded BEAM code and size of the code in process_main().
