The view tool was blindly loading binaries even for traces that have
encodings. This leads to fatal errors when binaries have changed, even
when the change has no impact on viewing a trace. We fix that here by
reading the filtype at init time.
Work around the #6942 crash by always setting the disasm syntax to DR style
for REGDEPS traces.
This change actually sets the disasm syntax to AT&T by default if no module
path is passed in; which is what it is supposed to do: but it was not doing
that and this breaks 3 tests comparing DR-style output. We put in a quick
fix to request DR style for those tests.
Tested locally where the view tool asserts without this fix.
