[HLSL] Missing LValue to RValue cast in implicit cast for HLSLAggregateSplatCast #163593
Description
HLSLAggregateSplatCast should always contain an lvalue to rvalue cast.
int1 A = {1};
int4 B = (int4)A;
In this example there is a missing LValue to RValue cast, so the truncation is resulting in an LValue. But before the HLSLVectorTruncation there should be an LValue to RValue cast.
