Hello!

Recently, gcc was switched to enable TFmode moves in XMM registers
also for TARGET_SSE. Sync reg-reg move cost calculation.

2012-07-14  Uros Bizjak  <ubizjak@gmail.com>

	* config/i386/i386.c (ix86_set_reg_reg_cost): Enable TFmode/TCmode
	for TARGET_SSE.

Tested on x86_64-pc-linux-gnu {,-m32}, committed to mainline SVN.

Uros.
