0454316c79 Bitcast all the bits of a floating point value, not just one. The zero 
extension is needed because the constructor for the Destination value
causes the APInt to have a bit width of 1.
Patch by Guoling Han.

1d48207f5b 1. Don't swap byte order in scanf. It isn't necessary and leads to 
incorrect results (canonicalization was dropped several commits ago).
2. Add support for fscanf.
3. Suppress a warning about cast to pointer from non-pointer-sized integer.

8c3d3dce2b For PR1293: 
* Rename the FunctionType* parameter from M to FT on all the functions.
* Implement a fix for PR1293 by just asserting that library functions that
  must return pointers should have pointer typed results. This just makes
  sure that we don't attempt to use an uninitialized integer or something
  later on.

40015aad5a Radically simplify execution. This patch gets rid of all the special 
handling for integer of various sizes. GenericValue now has just a single
integer field of type APInt. We use its facilities directly in the
execution of all instructions.

2d89fa84bc Remove the insufficient code in Interpreter::create that computed the 
Target DataLayout incorrectly. For now, we'll trust that the module has
got the correct DataLayout. In the future, this needs to be changed to
tell the TargetData to be "current host".

87aa65f40e Simplify things significantly because GenericValue now has a single integer 
field, of type APInt, instead of multiple integer fields. Also, get rid of
the special endianness code in StoreValueToMemory and LoadValueToMemory.
ExecutionEngine is always used to execute on the host platform so this is
now unnecessary.

4da5e17cfc From Dan Gohman: 
While preparing http://llvm.org/PR1198 I noticed several asserts
protecting unprepared code from i128 types that weren't actually failing
when they should because they were written as assert("foo") instead of
something like assert(0 && "foo"). This patch fixes all the cases that a
quick grep found.

2341c22ec7 Changes to support making the shift instructions be true BinaryOperators. 
This feature is needed in order to support shifts of more than 255 bits
on large integer types.  This changes the syntax for llvm assembly to
make shl, ashr and lshr instructions look like a binary operator:
   shl i32 %X, 1
instead of
   shl i32 %X, i8 1
Additionally, this should help a few passes perform additional optimizations.
