Certain environments, such as OS and embedded, benefit by using
the 64-bit IP-relative branch instruction (brl) for function calls.
Please enhance the IA-64 code generation to recognize the -mlong_calls
option (-mno_long_calls by default) and emit the brl.call instruction
instead of the br.call instruction when enabled.
