Avoid overwriting the APInt instance with 0 bytes which causes the bitwidth
to be set to 0 (illegal) producing a subsequent assert.

turn "putchar" calls into _IO_putc calls which is a lower-level interface.
This patch allows these calls to be executed by lli in interpreter mode.

results as the program executes.

extension is needed because the constructor for the Destination value
causes the APInt to have a bit width of 1.

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.

* 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.

2. Fix a copy & paste bug in StoreValueToMemory where 64-bit values were
truncated to 32

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.

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".

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.

execute any LLVM program using any bit width.

Move the getConstantExpr function towards the end of the file so we don't
need a dozen forward declarations.

2. Move a function to the Execution.cpp file where it belongs.

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.

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.
