951418b7e9 Implement printing of instruction result values when debug info is turned 
on. This helps to speed up the debugging time by showing computational
results as the program executes.

_t4:
        fmul f0, f3, f4
        fmadd f1, f1, f2, f0

instead of:

19dc32a2d4 Add some things needed by the llvm-gcc version supporting bit accurate integer 
types:
1. Functions to compute div/rem at the same time.
2. Further assurance that an APInt with 0 bitwidth cannot be constructed.
3. Left and right rotate operations.
4. An exactLogBase2 function which requires an exact power of two or it
   returns -1.

shown correctly, but arguments for function on top of stack are displayed incorrectly.

c767844fc9 This patch extends the LoopUnroll pass to be able to unroll loops 
with unknown trip counts. This is left off by default, and a
command-line option enables it. It also begins to separate loop
unrolling into a utility routine; eventually it might be made usable
from other passes.

It currently works by inserting conditional branches between each
unrolled iteration, unless it proves that the trip count is a
multiple of a constant integer > 1, which it currently only does in
the rare case that the trip count expression is a Mul operator with
a ConstantInt operand. Eventually this information might be provided
by other sources, for example by a pass that peels/splits the loop
for this purpose.
