MCSymbol - Instances of this class represent a symbol name in the MC file, and MCSymbols are created and uniqued by the MCContext class.
MCSymbols should only be constructed with valid names for the object file.
If the symbol is defined/emitted into the current translation unit, the Section member is set to indicate what section it lives in. Otherwise, if it is a reference to an external entity, it has a null section.

The alignment of the symbol, if it is 'common', or -1.
The alignment is stored as log2(align) + 1. This allows all values from 0 to 2^31 to be stored which is every power of 2 representable by an unsigned.

If a symbol has a Fragment, the section is implied, so we only need one pointer.
FIXME: We might be able to simplify this by having the asm streamer create dummy fragments. If this is a section, then it gives the symbol is defined in. This is null for undefined symbols, and the special AbsolutePseudoSection value for absolute symbols. If this is a variable symbol, this caches the variable value's section.
If this is a fragment, then it gives the fragment this symbol's value is relative to, if any.
For the 'HasName' integer, this is true if this symbol is named. A named symbol will have a pointer to the name allocated in the bytes immediately prior to the MCSymbol.
