[PECOFF] Create __ImageBase symbol. __ImageBase is a symbol having 4 byte integer equal to the image base address of the resultant executable. The linker is expected to create the symbol as if it were read from a file. In order to emit the symbol contents only when the symbol is actually referenced, we created a pseudo library file to wrap the linker generated symbol. The library file member is emitted to the output only when the member is actually referenced, which is suitable for our purpose. llvm-svn: 188052

[PECOFF] Fix __ImageBase symbol. __ImageBase is an absolute symbol whose address is the same as the image base address. What we did before this patch was to create __ImageBase symbol as a symbol whose *contents* (not location) is the image base address, which is clearly wrong. llvm-svn: 193565
