9535a84c33 Add PredicateSimplifier pass. Collapses equal variables into one form 
and simplifies expressions. This implements the optimization described
in PR807.

cc6d652824 Added some preliminary text to the TargetJITInfo class section. 
Fixed some inconsistencies with format. Corrected some of the text.

91f098c9f7 Add external definitions for commonly-used template specializations and add 
anchor methods to others.  This eliminates the vtable/template method bloat
in .o files that defining a cl::opt used to impose (~4K per .o file for one
cp::opt<unsigned>).

a72e220a25 New place to put compiler-specific functionality. This replaces Visibility.h, 
and provides macros that can be used to make explicit instantiations of
template specializations, which is a gcc-specific feature.

3c5fa40194 Fix target matching weights, so that ppc-darwin modules are codegen with the 
ppc target, not the itanium target, when run on an itanium machine.
This should fix the CodeGen/PowerPC regtest failures on itanium.
