alpha,arm,mips,power,riscv,sparc,x86,isa: De-specialize ExecContexts.
The ISA parser used to generate different copies of exec functions for each exec context class a particular CPU wanted to use. That's since been changed so that those functions take a pointer to the base ExecContext, so the code which would generate those extra functions can be removed, and some functions which used to be templated on an ExecContext subclass can be untemplated, or minimally less templated. Now that some functions aren't going to be instantiated multiple times with different signatures, there are also opportunities to collapse templates and make many instruction definitions simpler within the parser. Since those changes will be less mechanical, they're left for later changes and will probably be done in smaller increments.
