The important fix is that the constant interpolation value is stored in the
parameter slot P0, which is encoded as 2.
In addition, drop the SI_INTERP_CONST pseudo instruction, pass the parameter
slot as an operand to V_INTERP_MOV_F32 instead of hardcoding it there, and
add a special operand class for the parameter slots for type checking and
pretty printing.

Since functions with internal linkage don't have language linkage, it is valid
to overload them:
extern "C" {
static int foo();
static int foo(int);
}
So we mangle them.

if the offset fits in 11 bits. This makes use of the fact that the abi
requires sp to be 8 byte aligned so the actual offset can fit in 8
bits. It will be shifted left and sign extended before being actually used.
The assembler or direct object emitter will shift right the 11 bit
signed field by 3 bits. We don't need to deal with that here.

Vectors were being manually scalarized by the backend. Instead,
let the target-independent code do all of the work. The manual
scalarization was from a time before good target-independent support
for scalarization in LLVM. However, this forces us to specially-handle
vector loads and stores, which we can turn into PTX instructions that
produce/consume multiple operands.

'R600/SI: Use proper instructions for array/shadow samplers.' removed two
cases from TEX_SHADOW. Vincent Lejeune reported on IRC that this broke some
shadow array piglit tests with the r600g driver. Reinstating the removed
cases should fix this, and still works with radeonsi as well.
I will follow up with some lit tests which would have caught the regression.

This does two things:
It removes a call to abs() which may have "long long" parameter on Windows,
which is not necessarily available in C++03.
It also corrects the signedness of Amount, which was relying on
implementation-defined conversions previously.

function is successfully handled by fast-isel. That's because function
arguments are *always* handled by SDISel. Introduce FastLowerArguments to
allow each target to provide hook to handle formal argument lowering.
As a proof-of-concept, add ARMFastIsel::FastLowerArguments to handle
functions with 4 or fewer scalar integer (i8, i16, or i32) arguments. It
completely eliminates the need for SDISel for trivial functions.
