Summary: This patch (correctly) breaks some MSA tests by exposing the cases when SelectionDAG::getConstant() produces illegal types. These have been temporarily marked XFAIL and the XFAIL flag will be removed when SelectionDAG::getConstant() is fixed. There are three categories of failure: * Immediate instructions are not selected in one endian mode. * Immediates used in ldi.[bhwd] must be different according to endianness. (this only affects cases where the 'wrong' ldi is used to load the correct bitpattern. E.g. (bitcast:v2i64 (build_vector:v4i32 ...))) * Non-immediate instructions that rely on immediates affected by the previous two categories as part of their match pattern. For example, the bset match pattern is the vector equivalent of 'ws | (1 << wt)'. One test needed correcting to expect different output depending on whether big or little endian was in use. This test was test/CodeGen/Mips/msa/basic_operations.ll and experiences the second category of failure shown above. The little endian version of this test is named basic_operations_little.ll and will be merged back into basic_operations.ll in a follow up commit now that FileCheck supports multiple check prefixes.
