remove the DisablePatternForFastISel predicate, which is a check

that predated -fast-isel which attempted to speed up the dag pattern
matchers at -O0. Since fast-isel is around, this is basically
obsolete and removing it shrinks the generated dag isels.

Change LLVMConventionsChecker to accept an entire translation unit instead
...
of operating on each code decl. This exposes two flaws in AnalysisConsumer
that should eventually be fixed:
(1) It is not possible to associate multiple "actions" with a single
command line argument. This will require the notion of an
"analysis" group, and possibly tablegen support. (although eventually
we want to support dynamically loading analyses as well)
(2) AnalysisConsumer may not actually be scanning the declarations in namespaces.
We'll experiment first in LLVMConventionsChecker before changing the
behavior in AnalysisConsumer.

When complicated expressions are broken down into subexpressions
...
with multiplication by constants distributed through, occasionally
those subexpressions can include both x and -x. For now, if this

don't have simple identifiers (fixing a null dereference when scanning
