objtool: Handle Clang RSP musical chairs
For no apparent reason (possibly related to CONFIG_KMSAN), Clang can
randomly pass the value of RSP to other registers and then back again to
RSP. Handle that accordingly.
Fixes the following warnings:
drivers/input/misc/uinput.o: warning: objtool: uinput_str_to_user+0x165: undefined stack state
drivers/input/misc/uinput.o: warning: objtool: uinput_str_to_user+0x165: unknown CFA base reg -1
