ModuleSummaryAnalysis: Correctly handle refs from function inline asm to module inline asm.

If a function contains inline asm and the module-level inline asm
contains the definition of a local symbol, prevent the function from
being imported in case the function-level inline asm refers to a
symbol in the module-level inline asm.
