Re: [PATCH] MATCH: Look through VIEW_CONVERT when folding VEC_PERM_EXPRs.

The match.pd patterns to merge two vector permutes into one fail when a potentially no-op view convert expression is between the two permutes. This change lifts this restriction. gcc/ChangeLog: * match.pd: Allow no-op view_convert between permutes. gcc/testsuite/ChangeLog: * gcc.dg/fold-perm-2.
