da1f5b882a For PR950: 
This patch converts the old SHR instruction into two instructions,
AShr (Arithmetic) and LShr (Logical). The Shr instructions now are not
dependent on the sign of their operands.

6833ffe8b8 For PR950: 
Make necessary changes to support DIV -> [SUF]Div. This changes llvm to
have three division instructions: signed, unsigned, floating point. The
bytecode and assembler are bacwards compatible, however.

d414793dbc For PR950: 
This patch implements the first increment for the Signless Types feature.
All changes pertain to removing the ConstantSInt and ConstantUInt classes
in favor of just using ConstantInt.

5cd4ac0a79 Fix another dtor issue. The function local statics in this function were 
being destroyed at inconvenient times.  Switch to using non-local ManagedStatic
objects, which actually also speeds up ConstRules::get.

ee327e57d2 Implement a few symbolic constant folding things. X ? Y : Y is Y. 
Fold:
seteq ({ short }* cast (int 1 to { short }*), { short }* null)
setlt ({ short }* cast (int 1 to { short }*), { short }* cast (int 2 to { short }*))

to false/true.  These last two commonly occur in the output of compilers that
tag integers, like cozmic's scheme compiler.

63ba63bb56 Allow creation of GEP constantexprs with a vector of value* operands as 
well as a vector of constant*'s.  It turns out that this is more efficient
and all of the clients want to do that, so we should cater to them.

f8380b953a If we are trying to create a ConstantExpr cast that is really a GEP to the 
first element of an array, return a GEP instead of a cast.  This allows us
to transparently fold this:

int* getelementptr (int* cast ([100 x int]* %Gbody to int*), int 40)

into this:

int* getelementptr ([100 x int]* %Gbody, int 0, int 40)

d1b726d18f Implement folding of expressions like 'uint cast (int* getelementptr (int* 
null, uint 1) to uint)' to a constant integer.  We can only do this with
primitive LLVM types, because other types have target-specific sizes.

would always return false because the Type of a type value is always
Type::TypeTY and can never be a floating point type.

807e401607 Implement a bunch of symbolic constant folding opportunities. This implements 
testcase test/Regression/Assembler/ConstantExprFold.llx

Note that these kinds of things only rarely show up in source code, but are
exceedingly common in the intermediate stages of algorithms like SCCP.  By
folding things (especially relational operators) that use symbolic constants,
we are able to speculatively fold more conditional branches, which can
lead to some big simplifications.

It would be easy to add a lot more special cases here, so if you notice
SCCP missing anything "obvious", you know what to make smarter.  :)
