Subject: [PATCH 1/2] [DebugInfo] Enforce DISubprogram type as required in
LLParser
Add a parse-time check so that the LLParser treats the `type:` field of
DISubprogram as required and non-null, producing a clear parse-time
error ("missing required field 'type'" / "'type' cannot be null") in
addition to the existing verifier check added in #194556.
Update existing tests to supply a minimal valid type field where they
are not intentionally testing malformed debug info.

Subject: [PATCH 2/2] [DebugInfo] Fix mlir/test missing DISubprogram type
Add missing type: field to DISubprogram in
mlir/test/Target/LLVMIR/Import/global-variables.ll, missed by the
initial batch fix in the previous commit.
