This commit serializes the fixed stack objects, including fixed spill slots. The fixed stack objects are serialized using a YAML sequence of YAML inline mappings. Each mapping has the object's ID, type, size, offset, and alignment. The objects that aren't spill slots also serialize the isImmutable and isAliased flags. The fixed stack objects are a part of the machine function's YAML mapping. Reviewers: Duncan P. N. Exon Smith git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@242045 91177308-0d34-0410-b5e6-96231b3b80d8
