instcombine: Split out the __stpcpy_chk simplifications from StrCpyChkOpt
r166198 migrated the strcpy optimization to instcombine. The strcpy
simplifier that was migrated from Transforms/Scalar/SimplifyLibCalls.cpp
was also doing some __strcpy_chk simplifications. Those fortified
simplifications were migrated as well, but introduced a bug in the
__stpcpy_chk simplifier in the process. This happened because the
__strcpy_chk and __stpcpy_chk simplifiers were both mapped to StrCpyChkOpt
which was updated with simplifications that worked for __strcpy_chk, but
not __stpcpy_chk.
This patch fixes the problem by adding proper test coverage and creating a
new simplifier for __stpcpy_chk (instead of sharing one with __strcpy_chk).

The attached patch adds eValueTypeVector to lldb_private::Value. The nested struct Vector is patterned after RegisterValue::m_data.buffer. This change to Value allows ClangExpressionDeclMap::LookupDecl to return vector register data for consumption by InterpreterStackFrame::ResolveValue. Note that ResolveValue was tweaked slightly to allocate enough memory for vector registers.
An immediate result of this patch is that "expr $xmm0" generates the same results on Linux as on the Mac, which is good enough for TestRegisters.py. In addition, the log of m_memory.PrintData(data_region.m_base, data_region.m_extent) shows that the register content has been resolved successfully. On the other hand, the output is glaringly empty:

In the past "production" clang builds would not be used for c++, and
we had the -ccc-clang-cxx and -ccc-no-clang-cxx options to force them
on or off for testing.
Clang c++ support is now production quality and these options are dead.

Fix ARM's b.w instruction for thumb 2 and the encoding T4. The branch target
is 24 bits not 20 and the decoding needed to correctly handle converting the
J1 and J2 bits to their I1 and I2 values to reconstruct the displacement.

Ensuring that the swig typemaps for SBData set the size to 0 along with the pointer to NULL
There should be no functional changes as SBData creation functions already checked for NULL regardless of size - but it ensures consistency

Allow to fold vector load if there is more than one bitcast, so in the case:
%0 = load <8 x i16>* %dest
%1 = shufflevector <8 x i16> %0, <8 x i16> %in,
<8 x i32> < i32 0, i32 1, i32 2, i32 3, i32 13, i32 undef, i32 14, i32 14>
store <8 x i16> %1, <8 x i16>* %dest
We get:
vmovlpd (%eax), %xmm0, %xmm0
instead of:
vmovaps (%eax), %xmm1
vmovsd %xmm1, %xmm0, %xmm0
No extra test-case is added. I just fixed the existing one
(also it uses FileCheck now).
