[DebugInfo] Support for DW_AT_associated and DW_AT_allocated. Summary: This support is needed for the Fortran array variables with pointer/allocatable attribute. This support enables debugger to identify the status of variable whether that is currently allocated/associated. for pointer array (before allocation/association) without DW_AT_associated (gdb) pt ptr type = integer (140737345375288:140737354129776) (gdb) p ptr value requires 35017956 bytes, which is more than max-value-size with DW_AT_associated (gdb) pt ptr type = integer (:) (gdb) p ptr $1 = <not associated> for allocatable array (before allocation) without DW_AT_allocated (gdb) pt arr type = integer (140737345375288:140737354129776) (gdb) p arr value requires 35017956 bytes, which is more than max-value-size with DW_AT_allocated (gdb) pt arr type = integer, allocatable (:) (gdb) p arr $1 = <not allocated> Testing - unit test cases added - check-llvm - check-debuginfo Reviewed By: aprantl Differential Revision: https://reviews.llvm.org/D83544
