This is a regression caused by r106792 and caught by gdb testsuite.

Add variables into a scope before constructing scope DIE otherwise variables won't be included DIE tree.

DBG_VALUE machine instruction pointing to undefined register for a variable justify a separate scope if the variable is inlined function's argument.

switch from this:

  if (TimePassesIsEnabled) {
    NamedRegionTimer T(Name, GroupName);
    do_something();
  } else {
    do_something(); // duplicate the code, this time without a timer!
  }

to this:

  {
    NamedRegionTimer T(Name, GroupName, TimePassesIsEnabled);
    do_something();
  }

This speeds up local variable handling in DwarfDebug.

inlined function's arguments need a label to mark the start point because they are not directly attached to current function.

There is no need to force an line number entry (using previous location) for a temp label at unknown location.

llvm-svn: 104740

Identify instructions, that needs a label to mark debug info entity, in advance. This simplifies beginScope().

This is used to track variable information.

Split DbgVariable. Eventually, variable info will be communicated through frame index, or DBG_VALUE instruction, or collection of DBG_VALUE instructions. Plus each DbgVariable may not need a label.
