Currently, there are substantial problems forming vld1_dup even if the VDUP survives legalization. The lack of an actual node leads to terrible results: not only can we not form post-increment vld1_dup instructions, but we form scalar pre-increment and post-increment loads which force the loaded value into a GPR. This patch fixes that by combining the vdup+load into an ARMISD node before DAGCombine messes it up. Also includes a crash fix for vld2_dup (see testcase @vld2dupi8_postinc_variable). Recommiting with fix to avoid forming vld1dup if the type of the load doesn't match the type of the vdup (see https://llvm.org/bugs/show_bug.cgi?id=31404).
