98f0f26fdf InstrProf: Fix display of large numbers in llvm-cov
llvm-cov was truncating numbers that were larger than a particular
fixed width, which is as confusing as it is useless. Instead, we use
engineering notation with SI prefix for magnitude.

cc690d62e3 llvm-cov: Only emit colour by default if the output is a tty
This replaces the -no-color flag with a -color={auto|always|never}
option, with auto as the default, which is much saner.

bd59e21808 InstrProf: Remove xfails for big-endian from coverage tests
This still doesn't actually work correctly for big endian input files,
but since these tests all use little endian input files they don't
actually fail. I'll be committing a real fix for big endian soon, but
I don't have proper tests for it yet.

05b74bc4a6 InstrProf: Use the proftext format for these coverage tests
This format's easier to understand and update by hand.

90c4e8b70c InstrProf: Teach llvm-cov to show the max count instead of the last
When multiple regions start on the same line, llvm-cov was just
showing the count of the last one as the line count. This can be
confusing and misleading for things like one-liner loops, where the
count at the end isn't very interesting, or even "if" statements with
an opening brace at the end of the line.

Instead, use the maximum of all of the region start counts.

42b96889d1 llvm-cov: Fix dropped lines when filters were applied
Uncovered lines in the middle of a covered region weren't being shown
when filtering to a particular function.

6c7a6a1ba2 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'.
