compile.c (iseq_compile_each0): remove irrelevant tracecoverage

Browse Source 
This change removes tracecoverage instructions on a line that has any
NODE but is non-significant, such as, just one literal.

This fixes the following failure that occurs only when coverage is
enabled:

  1) Failure:
TestISeq#test_to_a_lines [.../ruby/test/ruby/test_iseq.rb:56]:
<[3, 4, 7, 9]> expected but was
<[3, 4, 5, 6, 7, 8, 9]>.
