Cover deleted all comments because they can break the simple way that
counters are injected into the rewritten source. But //go: comments have
semantic value, and for instance go test -cover runtime fails during
compilation because of their absence from the annotated source.
We can keep the //go: comments because they are at the beginning of
the line and are not affected by our counter injection.
Fixes#10270.
After this CL, go test -cover runtime works.
A testing strategy that does not involve a golden file would be welcome
but I can't think of one.

Given
x()
panic(1)
y()
the y should not show as covered.

Silly test added yesterday requires that some code in a goroutine executes.
Make sure it does.

Just missed a case (ha!) in the tree walk. Dup the code for an empty switch, add test.

This CL aims to fix the problem described here:

This makes it easier to parse via external tools such as editors. Editors can
show each function in a list and jump directly to each function with this
additional information. This pattern can be seen in other Go tools such as "go
test" in the form of:
--- FAIL: TestCover (0.52 seconds)

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.

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.

Phrases like "returns whether or not the image is opaque" could be
describing what the function does (it always returns, regardless of
the opacity) or what it returns (a boolean indicating the opacity).
Even when the "or not" is missing, the phrasing is bizarre.
Go with "reports whether", which is still clunky but at least makes
it clear we're talking about the return value.

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

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.
