  Log Message:
  -----------
  [CodeGen] Allow mixed scalar type constraints for inline asm (#65465)

GCC supports code like "asm volatile ("" : "=r" (i) : "0" (f))" where i
is integer type and f is floating point type. Currently this code
produces an error with Clang. The change allows mixed scalar types
between input and output constraints.
