d5427f5249 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.

a0792c722e Change an std::set to a SmallPtrSet. This speeds up the verifier on 
447.dealII from 1.27s to 0.86s.

02141c9762 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).

6301eb8919 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).

c2542fe089 make the datastructure used in BytecodeWriter::outputValueSymbolTable

98373d22fb 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.

dc8f129004 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%).

d043d112d0 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%).

b005a435cd 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.

27cff151e2 Fix clients like this: 
delete ParseBytecodeFile(InputFilename, 0, &ErrorMessage);
  llvm_shutdown();
  delete ParseBytecodeFile(InputFilename, 0, &ErrorMessage);

The primitive type objects failed to ressurect themselves after shutdown, leading
to crashes in clients that used them after llvm_shutdown().

This solution isn't wonderful, because we clearly have static ctors.  However,
the code it replaces was just as bad, so it's not a regression.

5796c232a4 1. constants can never occur in the symbol table. 
2. All function-level constants are now incorporated into the module-level
  constant pool, since the compaction table was removed.  Eliminate extra
  work to check for them.

This speeds up the bcwriter from 24.4s to 13.1s on 447.dealII and .73 -> .56s
on kc++ in a release build.
