[COFF] Don't hard-code the load configuration size The load configuration directory is a structure whose size varies as the OS gains additional functionality. To account for this, the structure's layout begins with a size field; this allows loaders to know which fields are available. However, LLD hard-coded the sizes (112 bytes for 64-bit and 64 for 32-bit). This means that we might not inform the loader of all the pertinent fields or we might claim that there are more fields than are actually present. To correctly account for this, the size field must be loaded from the _load_config_used symbol. N.B. The COFF spec is either wrong or out of date, the load configuration directory is not correctly documented in the specification: it omits the size field. llvm-svn: 263543
