Hexagon - Add peephole optimizations for zero extends.
* lib/Target/Hexagon/HexagonInstrInfo.td: Add patterns to combine a
sequence of a pair of i32->i64 extensions followed by a "bitwise or"
into COMBINE_rr.
* lib/Target/Hexagon/HexagonPeephole.cpp: Copy propagate Rx in the
instruction Rp = COMBINE_Ir_V4(0, Rx) to the uses of Rp:subreg_loreg.
* test/CodeGen/Hexagon/union-1.ll: New test.
* test/CodeGen/Hexagon/combine_ir.ll: Fix test.
