Eli Friedman 35211c6091 Final step of instcombine debuginfo; switch a couple more places over to InsertNewInstWith, and use setDebugLoc for the cases which can't be easily handled by the automated mechanisms.

Duncan Sands 085ad3b81a Stop trying to have instcombine preserve LCSSA form: this was not
effective in avoiding recomputation of LCSSA form; the widespread
use of instsimplify (which looks through phi nodes) means it was
not preserving LCSSA form anyway; and instcombine is no longer
scheduled in the middle of the loop passes so this doesn't matter
anymore.

Jay Foad 52131344a2 Remove PHINode::reserveOperandSpace(). Instead, add a parameter to
PHINode::Create() giving the (known or expected) number of operands.

Chris Lattner abb8eb2c63 fix instcombine merging GEPs through a PHI to only make the
result inbounds if all of the inputs are inbounds.

Duncan Sands 4581ddc123 Teach InstructionSimplify about phi nodes. I chose to have it simply
offload the work to hasConstantValue rather than do something more
complicated (such handling mutually recursive phis) because (1) it is
not clear it is worth it; and (2) if it is worth it, maybe such logic
would be better placed in hasConstantValue.  Adjust some GVN tests
which are now cleaned up much further (eg: all phi nodes are removed).

Chris Lattner f6befffbb2 fix PR6512, a case where instcombine would incorrectly merge loads
from different addr spaces.

Duncan Sands 19d0b47b1f There are two ways of checking for a given type, for example isa<PointerType>(T)
and T->isPointerTy().  Convert most instances of the first form to the second form.
Requested by Chris.
