Vedant Kumar bc6479850e [llvm-cov] Get rid of all invalid filename references
We used to append filenames into a vector of std::string, and then
append a reference to each string into a separate vector. This made it
easier to work with the getUniqueSourceFiles API. But it's buggy.

std::string has a small-string optimization, so you can't expect to
capture a reference to one if you're copying it into a growing vector.
Add a test that triggers this invalid reference to std::string scenario,
and kill the issue with fire by just using ArrayRef<std::string>
everywhere.

Vedant Kumar 627887b650 [llvm-cov] Add an API to prepare file reports (NFC)
It would be nice to prepare file reports (using the CoverageReport API)
without actually rendering them to the console. I plan on using this to
flesh out the 'index' files in the coverage views.

Justin Bogner 0ef7a2a250 llvm-cov: Actually use the command line arguments when reporting
This code didn't really make sense as is. If a filename is passed in,
the user obviously wants the coverage *for that file*, not *for
everything*.

Justin Bogner f91bc6cdd8 llvm-cov: Simplify coverage reports, fixing PR22575 in the process
PR22575 occurred because we were unsafely storing references into a
std::vector. If the vector moved because it grew, we'd be left
iterating through garbage memory. This avoids the issue by simplifying
the logic to gather coverage information as we go, rather than storing
it and iterating over it.

I'm relying on the existing tests showing that this is semantically
NFC, since it's difficult to hit the issue this fixes without
relatively large covered programs.

Chandler Carruth d9903888d9 [cleanup] Re-sort all the #include lines in LLVM using
utils/sort_includes.py.

I clearly haven't done this in a while, so more changed than usual. This
even uncovered a missing include from the InstrProf library that I've
added. No functionality changed here, just mechanical cleanup of the
include order.

Alex Lorenz e82d89cc37 llvm-cov: add code coverage tool that's based on coverage mapping format and clang's pgo.
This commit expands llvm-cov's functionality by adding support for a new code coverage
tool that uses LLVM's coverage mapping format and clang's instrumentation based profiling.
The gcov compatible tool can be invoked by supplying the 'gcov' command as the first argument,
or by modifying the tool's name to end with 'gcov'.
