merge revision(s) 53424,55509: [Backport #12517]

Browse source 
* test/coverage/test_coverage.rb: ignored test when enabled to coverage.
	  It lead to crash with `make test-all`.

	* compile.c (ADD_TRACE): ignore trace instruction on non-positive
	  line.

	* parse.y (coverage): get rid of ArgumentError when the starting
	  line number is not positive.  [ruby-core:76141] [Bug #12517]
