Fix a few issues with comdat handling on COFF. * Section association cannot use just the section name as many sections can have the same name. With this patch, the comdat symbol in an assoc section is interpreted to mean a symbol in the associated section and the mapping is discovered from it. * Comdat symbols were not being set correctly. Instead we were getting whatever was output first for that section. A consequence is that associative sections now must use .section to set the association. Using .linkonce would not work since it is not possible to change a sections comdat symbol (it is used to decide if we should create a new section or reuse an existing one). This includes r210298, which was reverted because it was asserting on an associated section having the same comdat as the associated section. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@210367 91177308-0d34-0410-b5e6-96231b3b80d8 2014-06-06 19:26:12 +00:00			`// CHECK: error: cannot make section associative with .linkonce`
