    Add testcase for PR10533 (inlined vars) and 10537 (inlined labels - disabled
    
    Partial testcase for PR10533 (inlined vars) and 10537 (inlined labels)
    currently we cannot use the full testcase since stap doesn't support
    probing multiple instances of inlined labels.
    
    * testsuite/systemtap.base/inlinedvars.exp: New file.
    * testsuite/systemtap.base/inlinedvars.stp: Likewise.
    * testsuite/systemtap.base/inlinedvars.c: Likewise.

    PR10533 inlined vars are not always found (dwflpp).
    
    dwflpp::find_variable_and_frame_base switched too early to "pyshical view"
    of die tree. We need to lookup the var in the "syntactical view" of the die
    tree first. Then when we see a DW_TAG_inlined_subroutine while walking the
    syntactical die tree as returned by dwarf_getscopes for a given variable
    to retrieve the frame base, then we need to switch to walking the physical
    die tree where the subroutine is inlined.
    
    * dwflpp.cxx (find_variable_and_frame_base): Don't immediately go to
      die_scopes, but lookup var first based on pc. Then switch "die branches"
      when searching for frame base and a DW_TAG_inlined_subroutine is
      encountered.

    PR10533 inlined vars are not always found (lo2c-test off-by-one).
    
    * loc2c-test.c (handle_variable): Set inner to zero after
      calling dwarf_getscopes_die(), for loop will increase inner.

    PR10533 loc2c doesn't resolve frame base correctly for inlined vars.
    
    When we see a DW_TAG_inlined_subroutine while walking the syntactical
    die tree as returned by dwarf_getscopes for a given variable to retrieve
    the frame base, then we need to switch to walking the physical die tree
    where the subroutine is inlined.
    
    * loc2c-test.c (handle_variable): Switch "die branches" when searching
      for frame base and a DW_TAG_inlined_subroutine is encountered.
