Hi! This patch allows vectorization of some loops that use bool (which is especially important now that we use bool more often even for stmts that weren't originally using bool in the sources), in particular (when bool is cast to an integer type, and the bool rhs has def stmts within the loop as either BIT_{AND,IOR,XOR}_EXPR, or just SSA_NAME assigns or bool -> another bool casts, or comparisons (tested recursively). In that case the pattern recognizer transforms the comparisons into COND_EXPRs using suitable integer type (the same width as the comparison operands) and other bools to suitable integer types with casts added where needed. The patch doesn't yet handle vectorization of storing into a bool array, I'll work on that later. Bootstrapped/regtested on x86_64-linux and i686-linux.
