[Committed] PR target/106640: Fix use of XINT in TImode compute_convert_gain.

Thanks to Zdenek Sojka for reporting PR target/106640 where an RTL checking
build reveals a thinko in my recent patch to support TImode shifts/rotates
in STV.  My "senior moment" was to inappropriately use XINT where I should
be using INTVAL of XEXP.

	(timde_scalar_chain::compute_convert_gain): Replace incorrect use
	of XINT with INTVAL (XEXP (src, 1)).
