x86/insn: Rename insn_decode() to insn_decode_from_regs()

Browse Source 
commit 9e761296c52dcdb1aaa151b65bd39accb05740d9 upstream.

Rename insn_decode() to insn_decode_from_regs() to denote that it
receives regs as param and uses registers from there during decoding.
Free the former name for a more generic version of the function.

No functional changes.
