instcombine transforms vector loads that are only used by
extractelement operations into a bitcast of the pointer,
then a gep, then a scalar load.  Disable this when the vector
only has one element, because it leads to infinite loops in
instcombine (PR4908).

This transformation seems like a really bad idea to me, as it
will likely disable CSE of vector load/stores etc and can be
better done in the code generator when profitable.  This

fix pasto

add getVectorOperand/getIndexOperand accessors to ExtractElementInst.
Fix some const correctness problems in SelectInst.

Simplify from my last change. Assert1 is a macro that makes its caller return,
so "Assert1(isa<>); cast<>" is a valid idiom.

Actually check the PHI node's odd-numbered operands for BasicBlock-ness, like
the comment said.

Fix an abort on a store of an empty struct member. getValue returns
null in the case of an empty struct, so don't try to call getNumValues
on it.

Verify types. Invalid types can be constructed when assertions are off.

Make the verifier more robust by avoiding unprotected cast<> calls. Notably,
Assert1(isa<>); cast<> is not safe as Assert1 does not terminate the program.

Fix PR4882, by making MemCpyOpt not dereference removed stores to get the
context for the newly created operations.

fix ComputeMaskedBits handling of zext/sext/trunc to work with vectors.
This fixes PR4905

add some comments to describe the invariants.

Reappy r80998, now that the GlobalOpt bug that it exposed on MiniSAT is fixed.

Fix a thinko: When lowering fneg with xor, bitcast the operands
from floating-point to integer first, and bitcast the result
back to floating-point. Previously, this test was passing by
falling back to SelectionDAG lowering. The resulting code isn't
as nice, but it's correct and CodeGen now stays on the fast path.

Add a testcase for the GlobalOpt inbounds fix.

Add inbounds to these getelementptrs, now that GlobalOpt requires this,
to preserve the meaning of these tests.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81166 91177308-0d34-0410-b5e6-96231b3b80d8

Don't commit stores with addresses that have indices that are not
compile-time constant integers or that are out of bounds for their
corresponding static array types. These can cause aliasing that
GlobalOpt assumes won't happen.

Don't commit addresses of aggregate values. This avoids problems with
an aggregate store overlapping a different aggregate store, despite
the stores having distinct addresses.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81164 91177308-0d34-0410-b5e6-96231b3b80d8

Fix GlobalOpt to avoid committing a store if the address getelementptr
is missing the inbounds flag. This is slightly conservative, but it
avoids problems with two constants pointing to the same address but
getting distinct entries in the Memory DenseMap.

Preserve the InBounds flag when evaluating a getelementptr instruction
into a getelementptr ConstantExpr.
