Really^2 fix <rdar://problem/8361834>, this time without crashing.
...
Now MICache is a linked list (per the FIXME), where we tradeoff between MacroInfo objects being in MICache
and MIChainHead. MacroInfo objects in the MICache chain are already "Destroy()'ed", so they can be reused. When
inserting into MICache, we need to remove them from the regular linked list so that they aren't destroyed more than
once.

Really fix: <rdar://problem/8361834> MacroInfo::AddTokenToBody() leaks memory
...
The problem was not the management of MacroInfo objects, but that when we recycle them
via the MICache the memory of the underlying SmallVector (within MacroInfo) was not getting
released. This is because objects stashed into MICache simply are reused with a placement
new, and never have their destructor called.

Simplify lifetime management of MacroInfo objects in Preprocessor by having the Preprocessor maintain them in a linked
...
list of allocated MacroInfos. This requires only 1 extra pointer per MacroInfo object, and allows us to blow them
away in one place. This fixes an elusive memory leak with MacroInfos (whose exact location I couldn't still figure
out despite substantial digging).
Fixes <rdar://problem/8361834>.
