This commit fixes a bug in the previous codegen for the `select` instruction when the operations of the `select` were of the `v128` type. Previously teh `XmmCmove` instruction only stored an `OperandSize` of 32 or 64 for a 64 or 32-bit move, but this was also used for these 128-bit types which meant that when used the wrong move instruction was generated. The fix applied here is to store the whole `Type` being moved so the 128-bit variant can be selected as well.

* x64: Fix codegen for the `i8x16.swizzle` instruction (#4318) This commit fixes a mistake in the `Swizzle` opcode implementation in the x64 backend of Cranelift. Previously an input register was casted to a writable register and then modified, which I believe instructions are not supposed to do. This was discovered as part of my investigation into #4315. * x64: Fix codegen for the `select` instruction with v128 (#4317) This commit fixes a bug in the previous codegen for the `select` instruction when the operations of the `select` were of the `v128` type.
