Jez Ng	63ace77962	[lld-macho] Initial support for common symbols ... On Unix, it is traditionally allowed to write variable definitions without initialization expressions (such as "int foo;") to header files. These are called tentative definitions. The compiler creates common symbols when it sees tentative definitions. When linking the final binary, if there are remaining common symbols after name resolution is complete, the linker converts them to regular defined symbols in a `__common` section. This diff implements most of that functionality, though we do not yet handle the case where there are both common and non-common definitions of the same symbol.
