Remove special handling of implicit_def. Fix a couple more bugs in liveintervalanalysis and coalescer handling of implicit_def.

Note, isUndef marker must be placed even on implicit_def def operand or else the scavenger will not ignore it. This is necessary because -O0 path does not use liveintervalanalysis, it treats implicit_def just like any other def.

For ExtVectorType, initializer is splatted to all elements.
For VectorType, initializer is bitcast to vector type.

Verified that for VectorType, output is identical to gcc.

Note that I'm guessing that *BSD and Solaris do the same thing as Linux 
here, but it's quite possible I'm wrong; if the following testcase 
gives an error on x86-64 with gcc for any of those operating systems, please
tell me:

#include <stdint.h>

int64_t x; long x;

Handle IMPLICIT_DEF with isUndef operand marker, part 2. This patch moves the code to annotate machineoperands to LiveIntervalAnalysis. It also add markers for implicit_def that define physical registers. The rest, is just a lot of details.

 - This more or less amounts to a revert of r65379. I'm curious to know what
   happened that caused this variable to become unused.

that function.

substitute those template arguments into the function parameter types
prior to template argument deduction. There's still a bit of work to
do to make this work properly when only some of the template arguments
are specified.

TypedRegion. While we plan on removing this code at some point, it serves as a
good reference implementation for use with BasicStore until we are sure the new
CastRegion logic (in RegionStore.cpp) is correct.

Fix: <rdar://problem/7021553> clang -fsyntax-only crashes (in ParseDeclarationSpecifiers ... from ParseObjCTypeName)

Another case where we should use SmallVector::data() instead of taking the
address of element 0 of a SmallVector when the SmallVector has no elements.
