linker: Speed up relocation with an 1-entry symbol cache
When relocating a DSO, it is not unusual to have consecutive
relocations using the same symbol. In this case, it is wasteful to
perform the same symbol lookup. This change implements an 1-entry
symbol cache so that symbol lookup results are reused in such scenario.
Test: On cuttlefish, enable STATS in linker_debug.h. Boot and see RELO
STATS in logcat showing cache hits. Hit rate seen is mostly
within 15% to 45%.
