Pete Cooper abcac11d1b Pack MCSymbol::Flags in to the bitfield with other members. NFC.
All file formats only needed 16-bits right now which is enough to fit
in to the padding with other fields.

This reduces the size of MCSymbol to 24-bytes on a 64-bit system.  The
layout is now

   0 | class llvm::MCSymbol
   0 |   class llvm::PointerIntPair SectionOrFragmentAndHasName
   0 |     intptr_t Value
     |   [sizeof=8, dsize=8, align=8
     |    nvsize=8, nvalign=8]

   8 |   unsigned int IsTemporary
   8 |   unsigned int IsRedefinable
   8 |   unsigned int IsUsed
   8 |   _Bool IsRegistered
   8 |   unsigned int IsExternal
   8 |   unsigned int IsPrivateExtern
   8 |   unsigned int Kind
   9 |   unsigned int IsUsedInReloc
   9 |   unsigned int SymbolContents
   9 |   unsigned int CommonAlignLog2
  10 |   uint32_t Flags
  12 |   uint32_t Index
  16 |   union
  16 |     uint64_t Offset
  16 |     uint64_t CommonSize
  16 |     const class llvm::MCExpr * Value
     |   [sizeof=8, dsize=8, align=8
     |    nvsize=8, nvalign=8]

     | [sizeof=24, dsize=24, align=8
     |  nvsize=24, nvalign=8]
