Also change some options that have different semantics (cause confusion) in llvm-readelf mode:
-s => -S
-t => --symbols
-sd => --section-data

There are no reasons for them to be STV_DEFAULT,
recently bfd did the same change.

visibility.
This patch is opposite to D19024, which made this symbols to be hidden by default.
Unfortunately FreeBSD loader wants to see
start_set_modmetadata_set/stop_set_modmetadata_set in the dynamic symbol table.
They were not placed there because had hidden visibility.
Patch makes them to have default visibility again.

Currently we don't check when creating relative relocations if the
section is read only or not. I am about to fix that, so first update the
patches that depend on the current behavior.

visibility.
These symbols describe a property of a linkage unit, so it seems reasonable
to limit their visibility to the linkage unit. Furthermore the use cases I
am aware of do not require more than hidden visibility.
This is a departure from the behavior of the bfd and gold linkers. However,
it is unclear that the decision to give these symbols default visibility
in those linkers was made deliberately. The __start_*/__stop_* feature
was added to the bfd linker in 1994 [1], while the visibility feature was
added about five years later [2], so it may have been that the visibility
of these symbols was not considered. The feature was implemented in gold
[3] in the same way; the behavior may have simply been copied from bfd.
The only related discussion I could find on the binutils mailing list [4]
was a user issue which would most likely not have occurred if the symbols
had hidden visibility.

A synthetic symbol can be global or local, and with the current
infrastructure we don't need any special code for it.
Fixes PR27228.
