  enable easier unittesting
* Added support for finding tabs in files, added to C++ linter

are doing that because the first DebugLoc object it sees is different from the
previous, which was nothing. Check for this situation, and don't emit one if
it's the first.

in-loop use is a PHI, it would return AllUsesAreAddresses as true.

with new/delete.  With disable-free, this reduces the number of 4/8 byte
mallocs from 4793/1541 to 865/456 and also drops other sizes as well.

This is a very small perf win, nothing major.

This fixes an assertion failure in BugReporter due to edge cases where no root
