Diego Novillo 418d0cf1c1 Support using sample profiles with partial debug info. ... Summary: When using a profile, we used to require the use -gmlt so that we could get access to the line locations. This is used to match line numbers in the input profile to the line numbers in the function's IR. But this is actually not necessary. The driver can provide source location tracking without the emission of debug information. In these cases, the annotation 'llvm.dbg.cu' is missing from the IR, but the actual line location annotations are still present. This patch adds a new way of looking for the start of the current function. Instead of looking through the compile units in llvm.dbg.cu, we can walk up the scope for the first instruction in the function with a debug loc. If that describes the function, we use it. Otherwise, we keep looking until we find one. If no such instruction is found, we then give up and produce an error.
