9b75edbd14 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.

8c1af7f5be 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.

16fd5641ad TableGen for fast isel seems to assume an 'imm' 
operand is the last in a pattern.  There is no
reason this should be true (although apparently
it always is right now).

c934b656f9 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.

316352b541 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!

Instcombine to be more aggressive about using SimplifyDemandedBits

e42a12bf0c When comparing DominanceFrontier's, advance iterators 
before erasing nodes, not after.  Otherwise dom frontier

b6fe72e457 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.

9e0f5a28dc Suppress the IV reversal transformation in the case that the RHS 
of the comparison is defined inside the loop. This fixes a
use-before-def problem, because the transformation puts a use
of the RHS outside the loop.

e1474eebee Split the ENABLE_THREADS #define in two. Now ENABLE_THREADS indicates the ability to run multiple threads at once in the JIT, and requires only 
mutex support.  LLVM_MULTITHREADED indicates (or will indicate) the ability to run LLVM itself across multiple threads, and requires atomics support.
