[dev.link] cmd/link: add generator symbols

Create a new class of symbols internal to the linker. These symbols live
in the Loader, and are real smybols, but have no data, only size. After
symbols are allocated in the binary in asmb() a function is called that
is responsible for filling in the data.

This allows the linker to create large symbols, but not pay the price on
the heap memory.
