quasilyte d487488135 cmd/internal/obj/x86: disallow PC/FP/SB scaled index 
Reject to compile I386/AMD64 asm code that contains
(Register)(PseudoReg*scale) forms of memory operands.
Example of such program: "CALL (AX)(PC*2)".
PseudoReg is one of the PC, FP, SB (but not SP).

When pseudo-register is used in register indirect as
scaled index base, x86 backend will panic because
its register file misses SB/FP/PC registers.

Fixes #12657.
