  -----------
  [ELF] Fix broken bitstream linking with lld when e_machine > 255

In ELF/InputFiles.cpp, getBitcodeMachineKind() is limited to uint8_t return
type. This works as long as EM_xxx is < 256, which is true for common
architectures, but not for some newly assigned or unofficial EM_* values.

The corresponding ELF field (e_machine) can hold uint16_t.
