Jay Foad 5bd375a6cc Convert CallInst and InvokeInst APIs to use ArrayRef.

Bill Wendling dd1cf3279e Inline check that's used only once.

Bill Wendling fb63d55fe8 Rework the logic (and removing the bad check for an unreachable block) so that 
the FailBB dominator is correctly calculated. Believe it or not, there isn't a
functionality change here.

Bill Wendling 220c9f045b Don't try to add stack protector logic to a dead basic block. It messes up 
dominator information.

Bill Wendling 96f962fdff In some cases, the "fail BB dominator" may be null after the BB was split (and 
becomes reachable when before it wasn't). Check to make sure that it's not null
before trying to use it.

Cameron Zwarich 4d7d728594 Fix the GCC test suite issue exposed by r127477, which was caused by stack 
protector insertion not working correctly with unreachable code. Since that
revision was rolled out, this test doesn't actual fail before this fix.

Cameron Zwarich 84986b298a Make more passes preserve dominators (or state that they preserve dominators if 
they all ready do). This removes two dominator recomputations prior to isel,
which is a 1% improvement in total llc time for 403.gcc.

The only potentially suspect thing is making GCStrategy recompute dominators if
it used a custom lowering strategy.

Owen Anderson 6c18d1aac0 Get rid of static constructors for pass registration. Instead, every pass exposes an initializeMyPassFunction(), which 
must be called in the pass's constructor.  This function uses static dependency declarations to recursively initialize
the pass's dependencies.

Clients that only create passes through the createFooPass() APIs will require no changes.  Clients that want to use the
CommandLine options for passes will need to manually call the appropriate initialization functions in PassInitialization.h
before parsing commandline arguments.

I have tested this with all standard configurations of clang and llvm-gcc on Darwin.  It is possible that there are problems
with the static dependencies that will only be visible with non-standard options.  If you encounter any crash in pass
registration/creation, please send the testcase to me directly.

Owen Anderson 755aceb5d0 Don't use PassInfo* as a type identifier for passes. Instead, use the address of the static 
ID member as the sole unique type identifier.  Clean up APIs related to this change.

Eric Christopher 2ad0c779c3 Fix up -fstack-protector on linux to use the segment 
registers.  Split out testcases per architecture and os
now.

Duncan Sands 9dff9bec31 Uniformize the names of type predicates: rather than having isFloatTy and 
isInteger, we now have isFloatTy and isIntegerTy.  Requested by Chris!

Benjamin Kramer d2564e3afb Move remaining stuff to the isInteger predicate.

Nick Lewycky 02d5f77d26 Remove VISIBILITY_HIDDEN from class/struct found inside anonymous namespaces. 
Chris claims we should never have visibility_hidden inside any .cpp file but
that's still not true even after this commit.

does.

Owen Anderson 1e5f00e7a7 This started as a small change, I swear. Unfortunately, lots of things call the [I|F]CmpInst constructors. Who knew!?

Duncan Sands af9eaa830a Rename PaddedSize to AllocSize, in the hope that this 
will make it more obvious what it represents, and stop
it being confused with the StoreSize.

Bill Wendling 6d8472b9cc When we split a basic block, there's a default branch to the newly created BB. 
Delete this default branch, because we're going to generate our own.
