Fix alignment of .comm and .lcomm on mingw32. For some reason .lcomm uses byte alignment and .comm log2 alignment so we can't use the same setting for both. Fix this by reintroducing the LCOMM enum. I verified this against mingw's gcc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163420 91177308-0d34-0410-b5e6-96231b3b80d8 2012-09-07 21:08:01 +00:00			`; RUN: llc -mtriple i386-pc-mingw32 < %s \| FileCheck %s`

WinCOFF: Emit common symbols as specified in the COFF spec Summary: Local common symbols were properly inserted into the .bss section. However, putting external common symbols in the .bss section would give them a strong definition. Instead, encode them as undefined, external symbols who's symbol value is equivalent to their size.
