32c67fd5da R600/SI: Fix int_SI_fs_interp_constant
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.

NOTE: This is a candidate for the Mesa stable branch.

85b0b97f34 include/llvm/Object/ELF.h: do debug checks only when NDEBUG
validateSymbol() is called all over the place, and it seems it's a debug check.
It significantly speedups llvm-symbolizer used in tsan/asan/msan. validateSymbol() is the second hot function and accounts for 15% of runtime.

1c56ae5a70 Use correct host/target CMake variables to define lit variables.
CMake and autotools disagree on what "host" means in a cross-compilation
context. Autotools (and lit) take it to be the machine the binaries being
compiled now will run on. CMake takes it to be the machine actually compiling
the binaries now.

This change makes lit.site-cfg more consistent between autotools and CMake,
allowing lit tests (particularly in ExecutionEngine) to run correctly when
cross-compiled with CMake

57e550e670 AArch64: stop claiming that NEON registers are usable for now.
If vector types have legal register classes, then LLVM bypasses LegalizeTypes
on them, which causes faults currently since the code to handle them isn't in
place.

This fixes test failures when AArch64 is the default target.

eff4f38af2 Fix some issues with rematerialization in RegisterCoalescer when the destination
of the copy is a subregister def. The current code assumes that it can do a full
def of the destination register, but it is not checking that the def operand is
read-undef. It also doesn't clear the subregister index of the destination in
the new instruction to reflect the full subregister def.

These issues were found running 'make check' with my next commit that enables
rematerialization in more cases.

cd4cd16ea7 Don't asume that a static function in an extern "C" block will not be mangled.
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.

29c7662732 Retain the name of the new internal global that's been shrunk.
It's possible (e.g. after an LTO build) that an internal global may be used for
debugging purposes. If that's the case appending a '.b' to it makes it hard to
find that variable. Steal the name from the old GV before deleting it so that
they can find that variable again.
