79a25ff8ec Use loop deletion instead of ADCE in these tests.

791223eac7 Clean ups for loop deletion based on Chris' feedback. 
Also, use SCEV to determine the trip count of the loop, which is more powerful
and accurate that Loop::getTripCount.

3e607df2f8 Fix this test. It was testing broken behavior in that it required ADCE to eliminate 
a potentially infinite loop, which is undesirable.  Instead, test the LICM behavior
that we're really interested in.

fe7f6bc9ce Revert the change from r51157 in 
test/Verifier/2002-11-05-GetelementptrPointers.ll, which was incorrect.
Instead, fix getIndexedType to not follow pointer types, as
PointerType is a subclass of CompositeType.

2da4145cd8 Fix a bug in LoopStrengthReduce that caused it to emit IR with 
use-before-def. The problem comes up in code with multiple PHIs where
one PHI is being rewritten in terms of the other, but the other needs
to be casted first. LLVM rules requre the cast instruction to be
inserted after any PHI instructions, but when instructions were
inserted to replace the second PHI value with a function of the first,
they were ended up going before the cast instruction. Avoid this
problem by remembering the location of the cast instruction, when one
is needed, and inserting the expansion of the new value after it.

This fixes a bug that surfaced in 255.vortex on x86-64 when
instcombine was removed from the middle of the loop optimization
passes.

c1d9f9604b Situations can arise when you have a function called that returns a 'void', but 
is bitcast to return a floating point value. The result of the instruction may
not be used by the program afterwards, and LLVM will happily remove all
instructions except the call. But, on some platforms, if a value is returned as
a floating point, it may need to be removed from the stack (like x87). Thus, we
can't get rid of the bitcast even if there isn't a use of the value.

768b6f281e Add CommonLinkage; currently tentative definitions 
are represented as "weak", but there are subtle differences
in some cases on Darwin, so we need both.  The intent
is that "common" will behave identically to "weak" unless
somebody changes their target to do something else.
No functional change as yet.

7e3ffb268e Do not generate by TableGen the hard-coded standard, target-independent part of 
DAG instruction selectors. Introudce a dedicated header file for this part:
include/llvm/CodeGen/DAGISelHeader.h

TableGen now only generates the include preprocessor directive to include this
new header.

This is a preparation for supporting multiple implementations of instruction
selectors in the future.
