fe24bd3a89 Add a NullFolder class that doesn't fold constants.
This may be used as the second IRBuilder template
parameter, the idea being that people learning LLVM
may find it helpful (several people asked on IRC
if it was possible to turn off constant folding
because it made it hard for them to see what was
going on).  Compiles, but otherwise completely
untested.

1e7f7865eb Make it possible to use different constant
folding policies with IRBuilder.  The default,
provided by ConstantFolder, is to do minimal
folding like now: what ConstantExpr provides.
An alternative is to use TargetFolder, which
uses target information to fold constants more.

1d85163ec2 Unbreak the llvm-gcc build: recent changes to
IRBuilder are not expecting null names.

1378c1dd22 Make 'Insert' set the name for Loads, instead of passing the name into the
LoadInst ctor, which causes std::string thrashing.

7a61d701c0 Have IRBuilder take a template argument on whether or not to preserve
names. This can save a lot of allocations if you aren't going to be
looking at the output.

d685181669 Rename the version of CreateRet that's a convenience method for creating
multiple-valued return values, so that the name CreateRet is just for
creating plain ret statements.

fc74abfba5 Enable first-class aggregates support.
Remove the GetResultInst instruction. It is still accepted in LLVM assembly
and bitcode, where it is now auto-upgraded to ExtractValueInst. Also, remove
support for return instructions with multiple values. These are auto-upgraded
to use InsertValueInst instructions.

The IRBuilder still accepts multiple-value returns, and auto-upgrades them
to InsertValueInst instructions.

creating global constant strings and pointers
to global constant strings.

25b825b3b8 Tweak IRBuilder to explicitly call the setName(const char*) method on Value
instead of passing the name into the instruction ctors.  Since most 
instruction ctors take their name as an std::string, this avoids copying the
string to the heap and a malloc and free.

Patch by Pratik Solanki!
