x32 Fast tracepoints: Customize jump pad address
MAP_32BIT is ignored on x32, meaning the jump pad can end up somewhere
between 2GB and 4GB, too far away from the executable for 5-byte
relative jumps (JMP rel32). So on x32, try explicitly placing the
jump pad near the middle of the available address space.

* linux-amd64-ipa.c (alloc_jump_pad_buffer) [__ILP32__]: Try
allocating around 0x80000000.
