For PR1194:
The bcreader counts on "primitive" types being inserted before they are
referenced in other types. With recent changes to the bcwriter, this fact
became exposed since IntegerType is no longer "primitive". We can no longer
count on all IntegerTypes being inserted early. This patch modifies
getOrCreateTypeSlot to insert any sub-type that can't possibly recurse
before we create the slot for the type. This has the benefit of reducing
the number of OpaqueType objects the reader needs to deal with.

Change the table datastructure to be a vector<smallvector>, instead of
vector<vector> to avoid allocations.  This speeds up bcwriting of 447.dealII
from 0.8276 to 0.7637s (8.4%).

This concludes this round of proding the bcwriter into submission.  Final
speedup from 24.4s to 0.7637s (32x).

Make BytecodeWriter::outputValueSymbolTable *significantly* less abusive
of memory, through a combination of DenseMap and SmallVector.  This speeds
up bcwriter on 447.dealII from 1.31s to 0.82s (60% faster).

make the datastructure used in BytecodeWriter::outputValueSymbolTable
*slightly* less abusive of memory.  This speeds up the bcwriter from
1.83s to 1.32s (39% faster) on 447.dealII.

Switch typemap over to DenseMap.  No significant speedup.

Switch NodeMap from an std::map to a DenseMap.  This speeds up bcwriting
of 447.dealII from 3.3s to 1.8s (80% faster).

The ModuleLevel vector is often quite sparse.  Switch it to a DenseMap.  This
speeds up bcwriting of 447.dealII by 40%, from 4.63s to 3.32s.

Allow DenseMAp to take an explicit DenseMapKeyInfo

Make the ModuleLevel datastructure more sane.  When a function-local value
is inserted into the table, it remembers that the value needs to be popped
off.  This makes purgeFunction much faster, speeding up bcwriting of 447.dealII
from 6.8->4.6s (47%).

Only compute the module levels info once per module, instead of once
per function.  This speeds up bcwriting on 447.dealII from 10.16s to 6.81s
(49%).

Clone and specialize CreateSlotIfNeeded into CreateFunctionValueSlot to handle
function-local values.  This speeds up bcwriting a small 2.2% (10.384->10.156s
on 447.dealII), but paves the way for more important changes.
