[flang] Use alias analysis in lowering record assignments (#176483)
Without alias analysis Flang assumes no aliasing in lowering record
assignments which can result in miscompilation of programs using
SEQUENCE types and EQUIVALENCE.
Represent `SEQUENCE` in fir.type.
For `SEQUENCE` types, use alias analysis to guard the fast path in
`genRecordAssignment`; otherwise fall back to element-wise expansion.
Update FIR FileCheck expectations
Add `FIRAnalysis` to `"flang/unittests/Optimizer/CMakeLists.txt"` to fix
the Windows x64 build failure (linker error).
Fixes #175246.
