Subject: Don't count debug info as instructions.  This was
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=d014761c9337f270f497aa960d51ee424bb166d5;p=oota-llvm.git

Don't count debug info as instructions.  This was
preventing the emission of the NOP on Darwin for a
function with no actual code.  From timberwolfmc
with TEST=optllcdbg.
