5cbf985dcb For PR1136: Rename GlobalVariable::isExternal as isDeclaration to avoid
confusion with external linkage types.

78d033e086 For PR411:
Take an incremental step towards type plane elimination. This change
separates types from values in the symbol tables by finally making use
of the TypeSymbolTable class. This yields more natural interfaces for
dealing with types and unclutters the SymbolTable class.

e4d87aa2de For PR950:
This patch removes the SetCC instructions and replaces them with the ICmp
and FCmp instructions. The SetCondInst instruction has been removed and
been replaced with ICmpInst and FCmpInst.

c27aa8ddb2 Delete the really inefficient method: void remove(const Type* Typ);
Speed up the symbol stripping code by avoiding a linear search of the
type table.

Get rid of removeEntry(type_iterator), since 'remove' is exactly the same
operation.

04cb800c32 This fixes PR531, a crash when running the CBE on a bytecode file.
The problem is that Function::renameLocalSymbols is iterating through
the symbol table planes, occasionally calling setName to rename a value
(which used to do a symbol table remove/insert pair).

The problem is that if there is only a single value in a particular type
plane that the remove will nuke the symbol table plane, and the insert
will create and insert a new one.  This hoses Function::renameLocalSymbols
because it has an iterator to the old plane, under the (very reasonable)
assumption that simply renaming a value won't cause the type plane to
disappear.

This patch fixes the bug by making the rename operation a single atomic
operation, which has a side effect of making the whole thing faster too. :)

1c06891186 Change SymbolTable::insertEntry to be more careful about how many map
lookups it does.  This shaves another 5% off of bcreading 252.eon.  Note that
the proper solution to this problem is to fix PR411, but that will have to
wait until later.

875510805f Made it illegal to pass a Type* through one of the Value* interfaces. The
SymbolTable will now assert if this is done. This didn't find any incorrect
usage of SymbolTable but will prevent future mistakes until Type != Value.

b870c5f7c5 Completely rewrote the class. SymbolTable now separates Type* from Value* in preparation\
for making Type not derive from Value. There are now separate interfaces \
for looking up, finding, and inserting Types and Values. There are also \
three separate iterator interfaces, one for type planes, one for the types \
(type type plane), and one for values within a type plane. See the \
documentation in the Header file.

7685ac8d35 This checkin basically amounts to a complete rewrite of the type-resolution
machinery.  This dramatically simplifies how things works, removes irritating
little corner cases, and overall improves speed and reliability.

Highlights of this change are:

1. The exponential algorithm built into the code is now gone.  For example
   the time to disassemble one bytecode file from the mesa benchmark went
   from taking 12.5s to taking 0.16s.
2. The linker bugs should be dramatically reduced.  The one remaining bug
   has to do with constant handling, which I actually introduced in
   "union-find" checkins.
3. The code is much easier to follow, as a result of fewer special cases.
   It's probably also smaller.  yaay.
