d6d0294e35 Teach IndVarSimplify's FixUsesBeforeDefs to handle InvokeInsts by
assuming that the use of the value is in a block dominated by the
"normal" destination. LangRef.html and other documentation sources
don't explicitly guarantee this, but it seems to be assumed in
other places in LLVM at least.

This fixes an assertion failure on the included testcase, which
is derived from the Ada testsuite.

FixUsesBeforeDefs is a temporary measure which I'm looking to
replace with a more capable solution.

382cb2189a Revert this. There's no way to verifiy indirect calls, and an optimizer can turn
indirect call into direct call, thus the verifier would reject something it
previously accepted.

9107c54693 Verify that calling conventions match function prototype.
This only rejects mismatches between target specific calling convention
and C/LLVM specific calling convention.
There are too many fastcc/C, coldcc/cc42 mismatches in the testsuite, these are
not reject by the verifier.

c5d73afa48 Tighten up the asserts in SmallVector::operator[]().
If this causes any new assertion failures that I didn't catch in
testing, the fix is usually to change "&v[0]" to "v.data()" for some
SmallVector v.

ef854af5bd Add a getAlignOf helper for getting the ABI alignment of a
type as a target independent constant expression.  I confess
that I didn't check that this method works as intended (though
I did test the equivalent hand-written IR a little).  But what
could possibly go wrong!

2ac8b324eb Fix for PR4235: to build a floating-point value from integer parts,
build an integer and cast that to a float.  This fixes a crash 
caused by trying to split an f32 into two f16's.

This changes the behavior in test/CodeGen/XCore/fneg.ll because that 
testcase now triggers a DAGCombine which converts the fneg into an integer
operation.  If someone is interested, it's probably possible to tweak 
the test to generate an actual fneg.
