Move alignment from MCSectionData to MCSection.
This starts merging MCSection and MCSectionData. There are a few issues with the current split between MCSection and MCSectionData. * It optimizes the the not as important case. We want the production of .o files to be really fast, but the split puts the information used for .o emission in a separate data structure. * The ELF/COFF/MachO hierarchy is not represented in MCSectionData, leading to some ad-hoc ways to represent the various flags. * It makes it harder to remember where each item is. The attached patch starts merging the two by moving the alignment from MCSectionData to MCSection. Most of the patch is actually just dropping 'const', since MCSectionData is mutable, but MCSection was not. llvm-svn: 237936
