ld: Limit cache size and add --max-cache-size=SIZE
When link_info.keep_memory is true, linker caches the relocation
information and symbol tables of input files in memory. When there
are many input files with many relocations, we may run out of memory.
Add --max-cache-size=SIZE to set the maximum cache size.
