d8f717911d fix PR8686, accepting a 'b' suffix at the end of all the setcc 
instructions.  I choose to handle this with an asmparser hack,
though it could be handled by changing all the instruction definitions
to allow be "setneb" instead of "setne".  The asm parser hack is
better in this case, because we want the disassembler to produce
setne, not setneb.

7509ccda93 When emitting a single function with cppgen=function, you don't want to emit 
initializers of global variables used in the function.
Also make sure to emit the operands of a constant.

f3d2f9d4be Another minor refactoring for VLD1DUP instructions.

classes instead of specifying it separately for each instruction.

8d41294664 Fix incorrect scheduling itineraries for NEON vld1/vst1 instructions. 
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.

82dc040d06 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.

c21a821e9f The srem -> urem transform is not safe for any divisor that's not a power of two. 
E.g. -5 % 5 is 0 with srem and 1 with urem.

ab5c703fdb Fix epilogue codegen to avoid leaving the stack pointer in an invalid 
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
