I added these instructions recently but I have no idea where these "1"
values in the NextCycles field came from.  As far as I can tell now,
these instruction stages are clearly intended to overlap.

 - I'm leaving MachO.h, because I believe it has external consumers, but I would really like to eliminate it (we have stylistic disagreements with one another).

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.

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

state. Previously Thumb2 would restore sp from fp like this:
mov sp, r7
sub, sp, #4
If an interrupt is taken after the 'mov' but before the 'sub', callee-saved
registers might be clobbered by the interrupt handler. Instead, try
restoring directly from sp:
add sp, #4
Or, if necessary (with VLA, etc.) use a scratch register to compute sp and
then restore it:
sub.w r4, r7, #8
mov sp, r7

In the attached testcase, the element was
never extracted (missing rotate).

extended later.
