f0c3081939 Teach globalsmodref-aa to track scalar pointer global variables which point 
to unaliased allocations.  Use this information to disambiguate pointers loaded
from them.  This is a very common case, so it's worthwhile to handle efficiently.

This implements Analysis/GlobalsModRef/indirect-global.ll

ed1e28e373 Fix a bug from r1.391 of this file, where we checked the size instead of 
the alignment when promoting allocations.  This implements

220e198fbe Now that ConstantBool::True/False are gone, we can modify Type.cpp to 
eliminate its static dtors, without having code that depends on order of
initialization.  Eliminate static ctors/dtors from Type.cpp.

0d237ceba1 Fix PR902: 
Errors are generated with the YYERROR macro which can only be called from
a production (inside yyparse) because of the goto statement in the macro.
This lead to several situations where GEN_ERROR was not called but
GenerateError was used instead (because it doesn't use YYERROR). However,
in such situations, catching the error much later (e.g. at the end of
the production) is not sufficient because LLVM can assert on invalid data
before the end of the production is reached. The solution is to ensure that
the CHECK_FOR_ERROR macro (which invokes YYERROR if there's an error) is
used as soon as possible after a call to GenerateError has been made.

deaf6398fc "Once more into the breach, dear friends, once more, or fill the wall up 
with our English dead."

No! Really! Serious this time...It was how the vreg uses were being
adjusted that was causing hte Olden tests to fail. I corrected this and
the Olden and Regression tests all passed.

cd762f5482 PR878: Instead of calculating the vreg to PHI use count everytime we get 
a function, do it up front in linear time (going through all of the
instructions once). We create a map out of them. Then it's no problem to
use the information in it during elimination...
