unresolved lookup expressions.

Owen Anderson 029eb7d243 Clarify the documentation of ext_vector, and add a small example. Hopefully 
this will alleviate some confusion about the existence of this feature.

Comments/improvements welcome.

Chris Lattner 57f064722a ppc/linux isn't ready for this and it was an accident that it was included. 
This should fix a bunch of linux buildbot failures.

Evan Cheng 67a69dd2ed Eliminate target hook IsEligibleForTailCallOptimization. 
Target independent isel should always pass along the "tail call" property. Change
target hook LowerCall's parameter "isTailCall" into a refernce. If the target
decides it's impossible to honor the tail call request, it should set isTailCall
to false to make target independent isel happy.

Chris Lattner fc2e376a15 use EmitLinkage for functions as well as globals. One output 
change is that we now use ".linkonce discard" for global variables
instead of ".linkonce samesize".  These should be the same, just less
strict.  If anyone is interested in mcizing MCSection for COFF targets,
this should be easy to fix.

Jakob Stoklund Olesen 0234628284 Fix inline cost predictions with SCIENCE. 
After running a batch of measurements, it is clear that the inliner metrics
need some adjustments:

Own argument bonus:       20 -> 5
Outgoing argument penalty: 0 -> 5
Alloca bonus:             10 -> 5
Constant instr bonus:      7 -> 5
Dead successor bonus:     40 -> 5*(avg instrs/block)

The new cost metrics are generaly 25 points higher than before, so we may need
to move thresholds.

With this change, InlineConstants::CallPenalty becomes a political correction:

if (!isa<IntrinsicInst>(II) && !callIsSmall(CS.getCalledFunction()))
  NumInsts += InlineConstants::CallPenalty + CS.arg_size();

The code size is accurately modelled by CS.arg_size(). CallPenalty is added
because calls tend to take a long time, so it may not be worth it to inline a
function with lots of calls.

All of the political corrections are in the InlineConstants namespace:
IndirectCallBonus, CallPenalty, LastCallToStaticBonus, ColdccPenalty,
NoreturnPenalty.

Jakob Stoklund Olesen 87256d8fe1 Revert test polarity to match comment and desired outcome. Remove undeserved bonus. 
A GEP with all constant indices is already considered free by
analyzeBasicBlock(), so don't give it an extra bonus in
CountCodeReductionForAlloca().

This patch should remove a small positive bias toward inlining functions with
variable-index GEPs, and remove a smaller negative bias from functions with
all-constant index GEPs.
