Remove support for parsing the "type i32" syntax for defining a numbered top level type without a specified number. This syntax isn't documented and blocks forward progress. llvm-svn: 133371

[X86][FastISel] Fix lowering of overflow result on AVX512 targets Summary: Fix a case where the overflow value of type i1, which is legal on AVX512, was assigned to a VK1 register class. We always want this value to be assigned to a GPR since the overflow return value is lowered to a SETO instruction. Fixes pr30981.
