Now that ShrinkDemandedOps() is separated out from DAG combine. It sometimes leave some obvious nops which dag combine used to clean up afterwards e.g. (trunk (ext n)) -> n. Look for them and squash them.

as a c expression that will be blatted out to the .inc

parsing C code :).

it isn't yet in TOT).

The major win of this is that the code is simpler and they 
print on the same line as the instruction again:

        movl    96(%esp), %eax          ## 4-byte Reload

into another AST, including their include history. Here's an example
error that involves a conflict merging a variable with different types
in two translation units (diagnosed in the third AST context into
which everything is merged).

/Volumes/Data/dgregor/Projects/llvm/tools/clang/test/ASTMerge/Inputs/var2.c:3:5:
error: external variable 'x2' declared with incompatible types in
different translation units ('int' vs. 'double')
int x2;

Although we maintain include history, we do not maintain macro
instantiation history across a merge. Instead, we map down to the
spelling location (for now!).

IntegerValType holds a uint32_t, so its constructor should take a uint32_t.  This allows it to be properly initialized with bit widths > 65535
