Intrinsic::va*.  This avoid conflicting with macros in the stdlib.h file.

9d20b71eca Represent va_list in interpreter as a (ec-stack-depth . var-arg-index) 
pair, and look up varargs in the execution stack every time, instead of
just pushing iterators (which can be invalidated during callFunction())
around.  (union GenericValue now has a "pair of uints" member, to support
this mechanism.) Fixes Bug 234.

34562bab04 Don't pass anything to the IntrinsicLowering class that is not_intrinsic, 
because that makes it abort. Also, fix a typo in a comment.

This checkin brought to you by the "It only takes about 30 seconds to run
ENABLE_LLI tests on Shootout on zion, even if they all dump core" fund.

2798cd077a Since we are using a gep_type_iterator, we apparently must get the type 
index by using I.getOperand() here. This was failing an assertion on
basically every struct access.

63438cc9b0 Add support for --debug-only=interpreter, to print out instrs before 
interpreting them.

Move support for getting the value of a ConstantExpr into
getConstantExprValue(), and add support for the rest of the different
kinds of ConstantExprs.  (I don't think I like ConstantExprs!)
This requires separate procedures executeShlInst() and executeShrInst().

Reduce the number of references to TheEE.

Get rid of an old comment mentioning annotations.

Fix exitCalled(), which was crashing the Interpreter. This was a
leftover from the return-value code refactoring.

8da17489aa Change LLI's internal representation of va_list to a pointer to the next 
argument to be returned by va_arg. This allows va_lists to be passed
between different LLVM procedures (though it is unlikely that an LLI
va_list would make sense to an external function, except by chance.)
