Patch by David Meyer, I added the test.

Updating MBlaze .mask and .frame directives to match GCC's output and fixing regression introduced in 120095 by checking MCStreamer::hasRawTextSupport.

llvm-svn: 120097

1. Fixing error where basic block labels were not being printed out when they need to be for the MBlaze backend because AsmPrinter::isBlockOnlyReachableByFallthrough does not take into account delay slots.
2. Re-adding .mask and .frame directives in printed assembly.
3. Adding .ent and .end directives in printed assembly.
4. Minor cleanups to MBlaze backend.

E.g. -5 % 5 is 0 with srem and 1 with urem.

Also addresses Frits van Bommel's comments.

constants.

We need to check if the individual vector elements are sign/zero-extended
values.  For now this only handles constants values.  Radar 8687140.

This allows to transform the rem in "1 << ((int)x % 8);" to an and.

Stylistic improvement suggested by Frits van Bommel.

fairly systematic way in instcombine.  Some of these cases were already dealt
with, in which case I removed the existing code.  The case of Add has a bunch of
funky logic which covers some of this plus a few variants (considers shifts to be
a form of multiplication), which I didn't touch.  The simplification performed is:
A*B+A*C -> A*(B+C).  The improvement is to do this in cases that were not already
handled [such as A*B-A*C -> A*(B-C), which was reported on the mailing list], and
also to do it more often by not checking for "only one use" if "B+C" simplifies.

remove that exception (InstructionSimplify handles this so there should
be no loss).

Refactor the ELFRelocationEntry (pull up) and move the arch-specific statics to inside the class where it belongs.

Next step is to rationally break apart the RecordRelocation()

Probably the step will be to have 1 member function for ech slot of the ELFRelocationEntry()
