4f0bd68cfe Add a "loses information" return value to APFloat::convert 
and APFloat::convertToInteger.  Restore return value to
IEEE754.  Adjust all users accordingly.

Breakage was exposed in the Ocaml bindings tests after Chris
uncommented an assertion in r55084.

folded, and remove bitcode reader/writer support for them.

da3db11db3 - 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.

a7c583d584 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.

ee9c30d435 Use push_back rather than operator[], which is incorrect in this cases. Unfortunately, this slow the testcase down a little bit, 
but only marginally.

79c69bc45f 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.

1ecaf45cf1 IR, bitcode reader, bitcode writer, and asmparser changes to 
insertvalue and extractvalue to use constant indices instead of
Value* indices. And begin updating LangRef.html.

There's definately more to come here, but I'm checking this 
basic support in now to make it available to people who are
interested.

edf0788758 Change the PointerType api for creating pointer types. The old functionality of PointerType::get() has become PointerType::getUnqual(), which returns a pointer in the generic address space. The new prototype of PointerType::get() requires both a type and an address space.

54dd24c2a7 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.
