Andrea Di Biagio 0736f445e3 [InlineFunction] Do not propagate the callsite debug location to instructions inlined from functions with debug info. ... When a function F is inlined, InlineFunction extends the debug location of every instruction inlined from F by adding an InlinedAt. However, if an instruction has a 'null' debug location, InlineFunction would propagate the callsite debug location to it. This behavior existed since revision 210459. Revision 210459 was originally committed specifically to workaround the lack of debug information for instructions inlined from intrinsic functions (which are usually declared with attributes `__always_inline__, __nodebug__`). The problem with revision 210459 is that it doesn't make any sort of distinction between instructions inlined from a 'nodebug' function and instructions which are inlined from a function built with debug info. This issue may lead to incorrect stepping in the debugger. This patch works under the assumption that a nodebug function does not have a DISubprogram. When a function F is inlined into another function G, InlineFunction checks if F has debug info associated with it. For nodebug functions, the InlineFunction logic is unchanged (i.e. it would still propagate the callsite debugloc to the inlined instructions). Otherwise, InlineFunction no longer propagates the callsite debug location.
