Linker script: Fix bug with several .bss When final image has several .bss sections, lld fails because second .bss always has zero VA. This causes link error "Not enough space for ELF and program headers" llvm-svn: 282067

Rewrite CommonInputSection as a synthetic input section. A CommonInputSection is a section containing all common symbols. That was an input section but was abstracted in a different way than the synthetic input sections because it was written before the synthetic input section was invented. This patch rewrites CommonInputSection as a synthetic input section so that it behaves better with other sections. llvm-svn: 286053
