5a58a65c10 Switch ValueSymbolTable to use StringMap<Value*> instead of std::map<std::string, Value*> 
as its main datastructure.  There are many improvements yet to be made, but
this speeds up opt --std-compile-opts on 447.dealII by 7.3%.

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

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).
