93c8d86be9 Validate the generated C++ code in llvmc tests. 
Checks that the code generated by 'tblgen --emit-llvmc' can be actually
compiled. Also fixes two bugs found in this way:

- forward_transformed_value didn't work with non-list arguments
- cl::ZeroOrOne is now called cl::Optional

c531da60aa Make 91378 more conservative. 
1. Only perform (zext (shl (zext x), y)) -> (shl (zext x), y) when y is a constant. This makes sure it remove at least one zest.
2. If the shift is a left shift, make sure the original shift cannot shift out bits.

6bf01a2caf You can't use typedefs to declare template member specializations, and 
clang enforces it.

e972f48c8f Initial work on disabling the scheduler. This is a work in progress, and this 
stuff isn't used just yet.

We want to model the GCC `-fno-schedule-insns' and `-fno-schedule-insns2'
flags. The hypothesis is that the people who use these flags know what they are
doing, and have hand-optimized the C code to reduce latencies and other
conflicts.

The idea behind our scheme to turn off scheduling is to create a map "on the
side" during DAG generation. It will order the nodes by how they appeared in the
code. This map is then used during scheduling to get the ordering.
