[PATCH] gdb/testsuite: add comments to line table from DWARF assembler

[Andrew Burgess <aburgess@redhat.com>]

Add comments to the assembler generated by the DWARF assembler that
builds the line table.  I found these comments useful when debugging
issues with the line table parsing.

This patch should make no difference to what is being tested.  The
test binaries should be unchanged after this commit.
