9d5245848ed242864c0e03d8bde4848a9bf9c744 [SCEV] Use depth limit for trunc analysis
Summary:
This fixes an extremely long compile time caused by recursive analysis
of truncs, which were not previously subject to any depth limits unlike
some of the other ops. I decided to use the same control used for
sext/zext, since the routines analyzing these are sometimes mutually
recursive with the trunc analysis.
