[BOLT][AArch64] Avoid UB due to shift of negative value. (#174994) ...

A build with LLVM_USE_SANITIZER=Undefined showed:

  bolt/lib/Target/AArch64/AArch64MCPlusBuilder.cpp:2277:60:
  runtime error: left shift of negative value -32768

This showed up in bolt/test/AArch64/veneer-lite-mode.s.

It is valid for ADRP's operand to be negative, and not valid to shift it
like that. To perform this shift reliably, cast the value to unsigned.
