Subject: [Ada] Enable traceback computation on ia64 platforms

Tested on ia64-linux, committed on mainline.

This patch enables tracebacks on ia64 platforms using the GCC DWARF-2
based unwinder mechanism. A value of -16 is used for the macro
PC_ADJUST because, since every call on ia64 is part of a 128 bit
bundle, an adjustment of minus 16 bytes from the point of return finds
the address of the previous bundle.
