92bdfe6951 Add, rewrite, and/or reformat many comments. 
Stop passing ostreams around: we already have one perfectly good ostream
and we can all share it.

Stop stashing a pointer to TargetData in the Pass object, because that will
lead to a crash if there are no functions in the module (ouch!)  Instead,
use addRequired() and getAnalysis(), like we always should have done.

Move the check for ConstantExpr up before the check for isPrimitiveType,
because we need to be able to catch e.g. ubyte (cast bool false to ubyte),
whose type is primitive but which is nevertheless a ConstantExpr, by calling
our specialized handler instead of the AsmWriter. This would result in
assembler errors when we would try to output something like ".byte (cast
bool false to ubyte)".

GC some unused variable declarations.

ad44ebfff0 IC: (X & C1) | C2 --> (X | C2) & (C1|C2) 
IC: (X ^ C1) | C2 --> (X | C2) ^ (C1&~C2)

We are now guaranteed that all 'or's will be inside of 'and's, and all 'and's
will be inside of 'xor's, if the second operands are constants.

79a8f09914 Fixed the enable/disable options. The AC_ARG_ENABLE macro does not perform 
the *action-if-not-given* code when the --disable option is used.
Rather, the AC_ARG_ENABLE macro sets the $enableval variable, which then needs
to be checked to determine if --enable, --disable, or neither was specified.
