[test] Replace `yaml2obj >` with `yaml2obj -o` and remove unneeded input redirection

[CodeView] Align type records on 4-bytes when emitting PDBs When emitting PDBs, the TypeStreamMerger class is used to merge .debug$T records from the input .OBJ files into the output .PDB stream. Records in .OBJs are not required to be aligned on 4-bytes, and "The Netwide Assembler 2.14" generates non-aligned records. When compiling with -DLLVM_ENABLE_ASSERTIONS=ON, an assert was triggered in MergingTypeTableBuilder when non-ghash merging was used. With ghash merging there was no assert. As a result, LLD could potentially generate a non-aligned TPI stream. We now align records on 4-bytes when record indices are remapped, in TypeStreamMerger::remapIndices().
