[mono] Fix the long opcode decompose pass when using llvm. (#56535)

It was replacing 64 bit opcodes with 32 bit ones while keeping the input/output 64 bit
vregs, leading to memory overwrites in later passes. Instead simply keep the 64
bit opcodes, llvm can handle them.

Fixes https://github.com/dotnet/runtime/issues/53546.
