By calling `uplevel $body` in the program proc (a pattern we use at many places), we can get rid of curly braces around each line number program directive. That seems like a nice small improvement to me. Change-Id: Ib327edcbffbd4c23a08614adee56c12ea25ebc0b

|

# table information. When multiple lines are given for the same
|
|
# address the compiler usually lists these in the order in which we
|
|
# would expect to encounter them. When stepping through nested inline

|
# the most inner frame, and this is what GDB displays.
|
|
#
|
|
# If we corrupt the order of the line table entries then GDB will
|
|
# display the wrong line as being the inner most frame.
