TableGen infers unmodeled side effects on instructions without a
pattern.  Fix some instruction definitions where that was overlooked.

Also raise an error if a rematerializable instruction has unmodeled side
effects. That doen't make any sense.

a watchpoint for either the variable encapsulated by SBValue (Watch) or the pointee
encapsulated by SBValue (WatchPointee).

Removed SBFrame::WatchValue() and SBFrame::WatchLocation() API as a result of that.

Modified the watchpoint related test suite to reflect the change.

Plus replacing WatchpointLocation with Watchpoint throughout the code base.

There are still cleanups to be dome.  This patch passes the whole test suite.
Check it in so that we aggressively catch regressions.

TableGen will mark any pattern-less instruction as having unmodeled side
effects. This is extra bad for V_SET0 which gets rematerialized a lot.

This was part of the cause for PR11125, but the real bug was fixed
in r141923.

When spilling around an instruction with a dead def, remember to add a
value number for the def.

The missing value number wouldn't normally create problems since there
would be an incoming live range as well.  However, due to another bug
we could spill a dead V_SET0 instruction which doesn't read any values.

The missing value number caused an empty live range to be created which
is dangerous since it doesn't interfere with anything.

This fixes part of PR11125.

Someone more familiar with LSR should double-check that the extra cast is actually doing the right thing in the overflow cases; I'm not completely confident that's that case.

then FileCheck will match the strings within the CHECK commands rendering

Fixed a case where we might end up trying to parse a type in the DWARF parser for a method whose class isn't currently in the process of completing itself. Currently, methods of a class, must be parsed when the class type that contains the method is asked to complete itself through the clang::ExternalASTSource virtual functions. Now we "do the right thing" by checking if the class is being defined, and if so we parse it, else we tell the class to complete itself so everything happens correctly.

Specifically, the expression parser used to use
functions attached to SymbolContext to do lookups,
but nowadays it searches a ModuleList or Module
directly instead.  These functions had no
remaining clients so I removed them to prevent
bit rot.

I also removed a stray callback function from
ClangExpressionDeclMap.

Enhance the memdep interface so that users can tell the difference between a dependency which cannot be calculated and a path reaching the entry point of the function. This patch introduces isNonFuncLocal, which replaces isUnknown in some cases.

which had previously been commented out while I tested
it.  It's not fully working yet, but it doesn't break
our testsuite and it's an important piece of
functionality.

Also added some logging to SymbolFileDWARF to help
diagnose entities that are found in a symbol file,
but do not reside in the expected namespace.

    Start handling debug line and scope information better:

    Migrate most of the location setting within the larger API in CGDebugInfo and
    update a lot of callers.
    Remove the existing file/scope change machinery in UpdateLineDirectiveRegion
    and replace it with DILexicalBlockFile usage.

context object.  Having it populated and registered
within a single FindExternalVisibleDecls call worked
fine when there was only one call (i.e., when we were
just looking in the global namespace).  

However, now FindExternalVisibleDecls is called for
nested namespaces as well, which means that it is
called not once but many times (once per module in
which the parent namespace appears).  This means that
the namespace mapping is built up across many calls
to the inferior FindExternalVisibleDecls, so I moved
it into a data structure (the search context) that is
shared by all calls.

I also added some logging to make it easier to see
what is happening during a namespace search, and 
cleaned up some existing logging.
