  Log Message:
  -----------
  [TableGen] RuleMatcher::defineComplexSubOperand avoid std::string copy. NFCI.

Use const reference to avoid std::string copy - accordingly to the style guide we shouldn't be using auto anyway.

Fixes MSVC analyzer warning.

  Log Message:
  -----------
  [X86][AVX] combineX86ShuffleChain - avoid bitcasts around insert_subvector() shuffle patterns.

We allow insert_subvector lowering of all legal types, so don't always cast to the vXi64/vXf64 shuffle types - this is only necessary for X86ISD::SHUF128/X86ISD::VPERM2X128 patterns later.
