Handle DW_FORM_data4 in read-debug-names.c
The recent .debug_names patches caused the writer to emit
DW_FORM_data4. Unfortunately the reader did not handle this form.
This patch updates the reader to handle a few DW_FORM_data* forms.
The complaint that is there went unnoticed -- I only found this when
debugging a failure in another series. More evidence, IMO, that
complaints should be removed.
I think the reason the failure itself went unnoticed is that the
symbol table code in gdb often works by accident, and in particular in
small programs like the ones in the test suite, it's often the case
that a CU will be expanded for some other reason, causing the test to
pass without really touching the index code. The aforementioned
series is aimed at fixing this.
It would probably be good to unify the abbrev/form code to some
degree, but it's mildly a pain as some forms don't make sense here and
because we recently discovered other issues with gdb's DW_FORM_data*
handling.
