[ELF] OVERLAY: support optional start address and LMA https://reviews.llvm.org/D44780 implemented rudimentary support for OVERLAY. The start address and `AT(ldaddr)` in `OVERLAY [start] : [NOCROSSREFS] [AT ( ldaddr )]` are not optional. In addition, there are two issues: * When the start address is `.`, subsequent sections don't share the address of the first overlay section. * When the first overlay section is empty and discardable, `p_paddr` is incorrectly zero. This is because a discarded section has a zero address, causing `prev->getLMA() + prev->size` where `prev` refers to the first section to evaluate to zero. This patch supports optional start address and LMA and fix the issues.
