8c7f24a36a add a fastpath to ConstantExpr::getBitCast to handle the case when an obviously 
unneeded bitcast is requested.  This is common for frontends who just unconditionally
cast even if the target is often the right type already.  THis prevents going into
getFoldedCast which switches on the opcode and does a bunch of other stuff before
doing the same opzn.

shift constant expressions, and add support for folding vector
shift constant expressions. This fixes PR3802.

0ff39b3feb - Re-apply 52748 and friends with fix. GetConstantStringInfo() returns an empty string for ConstantAggregateZero case which surprises selectiondag. 
- Correctly handle memcpy from constant string which is zero-initialized.

6d116bc7ce Revert (52748 and friends): 
Move GetConstantStringInfo to lib/Analysis. Remove
string output routine from Constant. Update all
callers. Change debug intrinsic api slightly to
accomodate move of routine, these now return values
instead of strings.

This unbreaks llvm-gcc bootstrap.

45e3958941 In ConstantArray::getAsString(), we know the size of the resultant string in advance so we can pre-allocate it and just fill in 
the entries.  This improves the time for the AsmPrinter on InstructionCombining.cpp from 0.4248s to 0.3370s.

fe63fb986d Implement address space attribute for LLVM pointer types. Address spaces are 
regions of memory that have a target specific relationship, as described in the 
Embedded C Technical Report. 

This also implements the 2007-12-11-AddressSpaces test, 
which demonstrates how address space attributes can be used in LLVM IR.

In addition, this patch changes the bitcode signature for stores (in a backwards 
compatible manner), such that the pointer type, rather than the pointee type, is 
encoded. This permits type information in the pointer (e.g. address space) to be 
preserved for stores.

LangRef updates are forthcoming.
