We want to make an if look like two blocks and have the coverage
report for the else block decorate the "else" keyword with the right
color. To do this, we adjust the apparent starting point of the else
block to include the "else".
The previous code assumed the way to do this was to move the
width of "else " backwards from the else block's opening brace, but
that assumes there is a space there. Instead, we now just start the
else block exactly at the end of the if block. Simpler, cleaner, and
fixes a bug.
Fixesgolang/go#8557.

Split the profile parsing code out of cmd/cover into
a reusable package, to support third-party coverage
tools.

Break the basic block at the function literal. The code to do this analysis
was already there; this CL just factors it out more nicely and uses it in
one new place. Also adds a test.

This requires a little more tree rewriting to put a block around the if of an "else if".
More tests too.

This number will allow us to give a conventional meaning to "coverage":
the percentage of executable statements visited by the test.

We are going to need one more piece of data, so rather than create
a third variable let's just put it all in one struct. The interface gets
easier too.

This is just the tool proper; stitching into "go test" will be a separate CL.
Tests are missing - they'll come once it's integrated - but it can handle,
perhaps correctly, all of src/pkg/...
The basic approach is to rewrite the source to add annotations that will
track coverage; the rewritten source must of course be compiled and
run after this tool has done its job.
