Backend: add debugwait function

Graphics / Beignet - Pan Xiuli [intel.com] - 24 November 2015 02:58 UTC

Use wait function to extend a debug function:
void debugwait(void) This function can hang the gpu unless gpu reset or host send something to let it go. EXTREMELY DANGEROUS for machines turn off hangcheck

v2: Fix some bugs, and add setting predicate and execwidth, also modify some inst scheduling

v3: Add push and pop in insturction selection, and set nomask with execwidth.

v4: Fix barrier predicate setting bugs, and rebase the patch
