tcg/i386: Add shortcuts for registers used in L constraint

While 64 bit hosts use the first three registers which are also used
as function input parameters, 32 bit hosts use TCG_REG_EAX and
TCG_REG_EDX which are not used in parameter passing.

After defining new register macros for the registers used in L
constraint, the patch replaces most occurrences of
tcg_target_call_iarg_regs0, tcg_target_call_iarg_regs1 and
tcg_target_call_iarg_regs2 by those new macros.

tcg_target_call_iarg_regs remains unchanged when it is used for input
arguments (only with 64 bit hosts) before tcg_out_calli.

A comment related to those registers was fixed, too.
