*	[ARM] Saturation instructions are DSP-only	Renato Golin	2016-07-25	1	-10/+20
\| \| \| \| \| \| \| \| \| \| \|	The saturation instructions appeared in v6T2, with DSP extensions, but they were being accepted / generated on any, with the new introduction of the saturation detection in the back-end. This commit restricts the usage to DSP-enable only cores. Fixes PR28607. llvm-svn: 276701
*	[ARM] Lower (select_cc k k (select_cc ~k ~k x)) into (SSAT l_k x)	Pablo Barrio	2016-06-23	1	-0/+215
	Summary: SSAT saturates an integer, making sure that its value lies within an interval [-k, k]. Since the constant is given to SSAT as the number of bytes set to one, k + 1 must be a power of 2, otherwise the optimization is not possible. Also, the select_cc must use < and > respectively so that they define an interval.
