Add #include raw_ostream.h in lib/Target/R600/SIFixSGPRCopies.cpp

This was casuing my release+asserts build on Windows to fail.

R600/SI: Remove redundant legalizeOperands call

When folding memory operands, preserve existing MachineMemOperands.

This comes into play with patchpoint, which can fold multiple
operands. Since the patchpoint is already treated as a call, the
machine mem operands won't affect anything, and there's nothing to
test. But we still want to do the right thing here to be sure that our
MIs obey the rules.

Teach the Makefile build system how to handle SOURCES which include
subdirectories. The only thing needed here is to create the appropriate
object file directories and add those as dependencies for the
compilation rules.

As a consequence, factor the non-source-file-specific dependencies for
compilation rules into a helper variable. This fixes an issue where the
project makefile wasn't actually a dependency of a bunch of compilation
make rules for no apparant reason.

This should have no observable effect for current makefile usage, but
will simplify how we build other libraries and is something CMake
already supports.

R600: Fix scheduling of instructions that use the LDS output queue

The LDS output queue is accessed via the OQAP register.  The OQAP
register cannot be live across clauses, so if value is written to the
output queue, it must be retrieved before the end of the clause.
With the machine scheduler, we cannot statisfy this constraint, because
it lacks proper alias analysis and it will mark some LDS accesses as
having a chain dependency on vertex fetches.  Since vertex fetches
require a new clauses, the dependency may end up spiltting OQAP uses and
defs so the end up in different clauses.  See the lds-output-queue.ll
test for a more detailed explanation.

To work around this issue, we now combine the LDS read and the OQAP
copy into one instruction and expand it after register allocation.

This patch also adds some checks to the EmitClauseMarker pass, so that
it doesn't end a clause with a value still in the output queue and
removes AR.X and OQAP handling from the scheduler (AR.X uses and defs
were already being expanded post-RA, so the scheduler will never see
them).

Include raw_ostream.h.

Including only Debug.h did not cause a compilation error, but you couldn't
do anything (like writing something with <<) to raw_ostreams returned by
llvm::dbgs() or llvm::errs() without including raw_ostream.h. So including
it from Debug.h should make sense.

Make all the conditional Mips 16 branches get initially set for the
short form. Constant islands will expand them if they are out of range.
Since there is not direct object emitter at this time, it does not
have any material affect because the assembler sorts this out. But we
need to know for the actual constant island work. We track the difference
by putting # 16 inst in the comments.

This reverts commit 194701. Apple's bootstrapped LTO builds have been failing,
and this change (along with compiler-rt 194702-194704) is the only thing on
the blamelist.  I will either reappy these changes or help debug the problem,
depending on whether this fixes the buildbots.
