Dan Gohman a5b9645c4b Split the Add, Sub, and Mul instruction opcodes into separate
integer and floating-point opcodes, introducing
FAdd, FSub, and FMul.

For now, the AsmParser, BitcodeReader, and IRBuilder all preserve
backwards compatability, and the Core LLVM APIs preserve backwards
compatibility for IR producers. Most front-ends won't need to change
immediately.

This implements the first step of the plan outlined here:

Nick Lewycky 206876e2da Use Operands.data() instead of &Operands[0] where Operands is a potentially
empty SmallVector.

Dan Gohman 8ded5d5884 Fix SCCP's handling of struct value loads and stores. SCCP doesn't
track individual leaf values in such cases, so it needs to treat
struct values as normal values in this case.

Dan Gohman fa1211f69b 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.

Gabor Greif f45ff35bfe Rename the last test with .llx extension to .ll, resolve duplicate test by renaming to isnan2. Now that no test has llx ending there is no need to search for them from dg.exp too.

Chris Lattner 5a58a4dc6d Rewrite multiple return value handling in SCCP. Before, the -sccp pass
would turn every getresult instruction into undef.  This helps with

Chris Lattner 1b706dd680 Fix PR1938 by forcing the code that uses an undefined value to branch one
way or the other.  Rewriting the code itself prevents subsequent analysis
passes from making contradictory conclusions about the code that could 
cause an infeasible path to be made feasible.

Reid Spencer a551c041f9 For PR1319:
Upgrade to use new Tcl exec based test harness. This exposes 3 bugs that
were previously not being reported:
test/Transforms/GlobalDCE/2002-08-17-FunctionDGE.ll
test/Transforms/GlobalOpt/memset.ll
test/Transforms/IndVarsSimplify/exit_value_tests.llx

Reid Spencer 9f9fe70b11 Add the SCCP regression tests for APInt expressions. These test cases
turned up some regressions that have since been fixed. We don't want to
loose the regression tests.

Test cases by Guoling Han.

Reid Spencer d029c7e666 Make the llvm-runtest function much more amenable by eliminating all the
global variables that needed to be passed in. This makes it possible to
add new global variables with only a couple changes (Makefile and llvm-dg.exp)
instead of touching every single dg.exp file.
