Alastair Houghton 8678ead796 [Linux] Improve backtracer ELF/DWARF parsing performance.
On Linux we use FileImageSource to read data from ELF images.  We were
doing this in a fairly naive manner, which turns out to be a performance
issue with larger statically linked binaries on Linux.

Change FileImageSource to use mmap() instead.
