`unless` statement was a syntactic sugar for `if` statement,
which made the result of branch coverage hard to understand.

This is needed for passing to the hook function the measuring target
type (line/branch/method) and the site of coverage event fired.

When no instruction is emitted in `iseq_compile_each0`
(i.e., when the line has no significant code), trace
instruction for `RUBY_EVENT_LINE` has been optimized out.
But trace for `RUBY_EVENT_COVERAGE` has not been removed.
Now, it is also removed.
`TestISeq#test_to_a_lines` has failed a long time under
coverage measurement (`make test-all COVERAGE=true`).
This change makes it pass.

To prepare new measuring targets: branch and method coverages.
So far, iseq->coverage was an array of counts executed for line coverage.
Now, it is a three-element array for each measuring target,
whose first element is an array for line coverage.
The second element is planned for branch coverage, and the third will be
for method coverage.

* compile.c (iseq_compile_each0): as compile_flip_flop always ends
with a jump instruction, successive instruction is never reached,
but caused stack consistency error without peephole optimization.

very rarely (or never, actually) useful to debug instruction
sequence. COMPILE_ERROR is usually SyntaxError, or fatal error
