to run the die pass after it.

7872171767 Rename AddUsesToWorkList -> AddUsersToWorkList, as that is what it does. 
Create a new AddUsesToWorkList method
optimize memmove/set/cpy of zero bytes to a noop.

f14fbb1a0b A pass that uses the generic CodeExtractor to rip out *every* loop in every 
function, as long as the loop isn't the only one in that function. This should
help debugging passes easier with BugPoint.

26e90f8776 A generic code extractor: given a list of BasicBlocks, it will rip them out into 
a new function, taking care of inputs and outputs.

0f91ce52a0 My previous commit broke the jit. The shift instructions always take 
an 8-bit immediate. So mark the shifts that take immediates as taking
an 8-bit argument. The rest with the implicit use of CL are marked
appropriately.

A bug still exists:

def SHLDmri32  : I2A8 <"shld", 0xA4, MRMDestMem>, TB;           // [mem32] <<= [mem32],R32 imm8

The immediate in the above instruction is 8-bit but the memory
reference is 32-bit. The printer prints this as an 8-bit reference
which confuses the assembler. Same with SHRDmri32.

d0574b7bd2 Regression tests for PR258 and PR259. 
2004-02-26-FPNotPrintableConstants.llx ensures that constants used in an
LLVM program are declared static if they are assigned to global variables.
2004-02-26-LinkOnceFunctions.llx ensures that linkonce functions get the
weak attribute.

0b01bff060 Fixes for PR258 and PR259. 
Functions with linkonce linkage are declared with weak linkage.
Global floating point constants used to represent unprintable values
(such as NaN and infinity) are declared static so that they don't interfere
with other CBE generated translation units.
