c60efbcee1 My fix for PR274 broke the build on Darwin/PPC. As I'm fairly certain this 
bug only affects Linux systems that use GLIBC, I'm going to put ifdefs around
the array.

acf93be258 Address PR274 - '[JIT] Programs cannot resolve the fstat function' 
by trying to get the compiler to generate an undefined reference for it
and related functions which live in libc_nonshared.a on Linux.

Linkers... sigh.

aba4159be8 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.

7824ed3d12 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.

46fdc8ce43 Add new ExecutionEngine::getGlobalValueAtAddress method, which can efficiently 
turn a memory address back into the LLVM global object that starts at that
address.  Note that this won't cause any additional datastructures to be built
for clients of the EE that don't need this information.

Also modified some code to not access the GlobalAddress map directly.

cd8f92bc62 Cleanup the JIT as per PR176. This renames the VM class to JIT, and merges the 
VM.cpp and JIT.cpp files into JIT.cpp.  This also splits some nasty code out
into TargetSelect.cpp so that people hopefully won't notice it.  :)

fb0c4c3d39 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.

e7599245cb 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.

acb0d474e9 Go back to allocating memory for each constant separately. Since SPARCs do not 
allow unaligned loads, that is probably the problem I've been seeing in numerous
SPARC test cases failing. X86, on the other hand, just slows down unaligned
accesses, since it must make 2 aligned accesses for each unaligned one.

d966bbe9bf 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.)
