[PECOFF] Remove COFF header from PE header for simplicity. COFF header is always present both in executable and in object file. PE header is present only in executable. So the natural way to handle PE/COFF file is treating COFF is mandatory header and PE is optional. Current data structre does not allow it, because PE header includes COFF header. Removing COFF header will simplify the code to handle PE/COFF files.

This patch improves the MCJIT runtime dynamic loader by adding new handling of zero-initialized sections, virtual sections and common symbols and preventing the loading of sections which are not required for execution such as debug information. Patch by Andy Kaylor! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154610 91177308-0d34-0410-b5e6-96231b3b80d8

This patch adds new functions to the SectionRef and ObjectFile interfaces to determine whether or not a section is meant to be read-only. These functions will be used by the MCJIT RuntimeDyld to give hints to the memory manager during the object loading process in a future patch.

Fixed ObjectFile functions: - getSymbolOffset() renamed as getSymbolFileOffset() - getSymbolFileOffset(), getSymbolAddress(), getRelocationAddress() returns same result for ELFObjectFile, MachOObjectFile and COFFObjectFile. - added getRelocationOffset() - fixed MachOObjectFile::getSymbolSize() - fixed MachOObjectFile::getSymbolSection() - fixed MachOObjectFile::getSymbolOffset() for symbols without section data. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145408 91177308-0d34-0410-b5e6-96231b3b80d8
