Clean up gdb.trace/entry-values.exp
This patch is to clean up gdb.trace/entry-values.exp as a preparation
of the next patch. It updates the comments to reflect the code.
One DIE generated in dwarf assembler is
GNU_call_site {
{low_pc "$bar_start + $bar_call_foo" addr}
{abstract_origin :$foo_label}
the DW_AT_low_pc attribute is the return address after the call, so I
rename variable bar_call_foo to returned_from_foo.
gdb/testsuite:

* gdb.trace/entry-values.exp: Update comments. Rename variable
bar_call_foo to returned_from_foo.
