compile.c (iseq_set_sequence): fix branch coverage table
Not only TRACE_ELEMENT but also INSN_ELEMENT may have events. The old pc2branchindex was created using only events of TRACE_ELEMENTs. This change uses events of INSN_ELEMENTs too for pc2branchindex table. [Bug #15476] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@66676 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
