Add support for the R_ARM_TARGET1 relocation, which should be given to relocations applied to all C++ constructors and destructors.

This enables the linker to match concrete relocation types (absolute or relative) with whatever library or C++ support code is being linked against.

.	"fptosi" and "fptoui" IR instructions are defined with round-to-zero rounding mode.
.	Currently for AVX mode for <4xdouble> and <8xdouble>  the "VCVTPD2DQ.128" and "VCVTPD2DQ.256" instructions are selected (for .fp_to_sint. DAG node operation ) by AVX codegen. However they use round-to-nearest-even rounding mode.
.	Consequently, the conversion produces incorrect numbers.
 
The fix is to replace selection of VCVTPD2DQ instructions with VCVTTPD2DQ instructions. The latter use truncate (i.e. round-to-zero) rounding mode. 
As .fp_to_sint. DAG node operation is used only for lowering of  "fptosi" and "fptoui" IR instructions, the fix in X86InstrSSE.td definition file doesn.t have an impact on other LLVM flows.
 
The patch includes changes in the .td file, LIT test for the changes and a fix in a legacy LIT test (which produced asm code conflicting with LLVN IR spec).

ConstantVector.  Fix some outright bugs in the implementation of
ConstantArray and Constant struct, which would cause us to not make
one big UndefValue when asking for an array/struct with all undef
elements.  Enhance Constant::isAllOnesValue to work with
ConstantDataVector.

to reduce the number of cast<>'s we have.  This allows someone to use
things like Ty->getVectorNumElements() instead of 
cast<VectorType>(Ty)->getNumElements() when you know that a type is a
vector.

It would be a great general cleanup to move the codebase to use these,
I will do so in the code I'm touching.
