This function is responsible for majority of CPU time in prefetto. Reduce the number of memory reads (don't read strings byte-by-byte). Update all calls of ReadString to include the third parameter to have a max read. Add an Elf creation benchmark since this function is on the elf creation path. Test: libunwindstack_unit_test Change-Id: Ia36e1f1a5ba76c9e9f13c43fb9e3691dde7897f2
