98a42b2fc3 fix PR9856, an incorrectly conservative assertion: a global can be 
"stored once" even if its address is compared.

5ea5c61589 Just because a GlobalVariable's initializer is [N x { i32, void ()* }] doesn't 
mean that it has to be ConstantArray of ConstantStruct. We might have
ConstantAggregateZero, at either level, so don't crash on that.

Also, semi-deprecate the sentinal value. The linker isn't aware of sentinals so
we end up with the two lists appended, each with their "sentinals" on them.
Different parts of LLVM treated sentinals differently, so make them all just
ignore the single entry and continue on with the rest of the list.

18a2e50a9b Add back a couple checks removed by r129128; the fact that an intitializer 
is an array of structures doesn't imply it's a ConstantArray of
ConstantStruct.

2c44a80d99 llvm.global_[cd]tor is defined to be either external, or appending with an array 
of { i32, void ()* }. Teach the verifier to verify that, deleting copies of
checks strewn about.

081c34b725 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.
