Chris claims we should never have visibility_hidden inside any .cpp file but
that's still not true even after this commit.

the new predicates I added) instead of going through a context and doing a
pointer comparison. Besides being cheaper, this allows a smart compiler
to turn the if sequence into a switch.

used to support GlobalVariables storing MDNodes, back when they were derived
from Constant before the introduction of NamedMDNode, but never removed.

In getMallocArraySize(), fix bug in the case that array size is the product of 2 constants.
Extend isArrayMalloc() and getMallocArraySize() to handle case where malloc is used as char array.
Ensure that ArraySize in LowerAllocations::runOnBasicBlock() is correct type.
Extend Instruction::isSafeToSpeculativelyExecute() to handle malloc calls.
Add verification for malloc calls.

Also break the type verification stuff into its own TypeSet to keep the
Verifier pass from becoming an AbstractTypeUser.

change as types are refined. Remove abstract types from CheckedTypes when they
we're informed that they have been refined. The only way types get refined in
the verifier is when later function passes start optimizing. Fixes PR4970.

so "Assert1(isa<>); cast<>" is a valid idiom.
Actually check the PHI node's odd-numbered operands for BasicBlock-ness, like
the comment said.

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

This adds location info for all llvm_unreachable calls (which is a macro now) in
!NDEBUG builds.
In NDEBUG builds location info and the message is off (it only prints
"UREACHABLE executed").

Make llvm_unreachable take an optional string, thus moving the cerr<< out of
line.
LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for
NDEBUG builds.

failures.
To support this, add some utility functions to Type to help support
vector/scalar-independent code. Change ConstantInt::get and
ConstantFP::get to support vector types, and add an overload to
ConstantInt::get that uses a static IntegerType type, for
convenience.
Introduce a new getConstant method for ScalarEvolution, to simplify
common use cases.
