*	Add bundle aware API for querying instruction properties and switch the code	Evan Cheng	2011-12-07	1	-1/+1

For properties like mayLoad / mayStore, look into the bundle and if any of the bundled instructions has the property it would return true. For properties like isPredicable, only return true if all of the bundled instructions have the property. For properties like canFoldAsLoad, isCompare, conservatively return false for bundles. llvm-svn: 146026

*	Introduce a pass to insert vzeroupper instructions to avoid AVX to	Bruno Cardoso Lopes	2011-08-23	1	-0/+105
	SSE transition penalty. The pass is enabled through the "x86-use-vzeroupper" llc command line option. This is only the first step (very naive and conservative one) to sketch out the idea, but proper DFA is coming next to allow smarter decisions. Comments and ideas now and in further commits will be very appreciated. llvm-svn: 138317
