DomainValues that are only used by "don't care" instructions are now
collapsed to the first possible execution domain after all basic blocks
have been processed.  This typically means the PS domain on x86.

For example, the vsel_i64 and vsel_double functions in sse2-blend.ll are
completely collapsed to the PS domain instead of containing a mix of
execution domains created by isel.

 a) adds a new --synchronicity (-s) setting for "command script add" that allows the user to decide if scripted commands should run synchronously or asynchronously (which can make a difference in how events are handled)
 b) clears up several error messages
 c) adds a new --allow-reload (-r) setting for "command script import" that allows the user to reload a module even if it has already been imported before
 d) allows filename completion for "command script import" (much like what happens for "target create")
 e) prevents "command script add" from replacing built-in commands with scripted commands
 f) changes AddUserCommand() to take an std::string instead of a const char* (for performance reasons)
plus, it fixes an issue in "type summary add" command handling which caused several test suite errors

Add a bunch of calls to RemoveDeadNode in LegalizeDAG, so legalization doesn't get confused by CSE later on.  Fixes PR11318.

duplicate the implicit getter lookup.  So, trust the
getter lookup that was already done in these cases.

The enterBasicBlock() function is combining live-out values from
predecessor blocks.  The RPO traversal means that more predecessors
have been visited when that happens, only back-edges are missing.

initial declaration. Previously, we would wait until later to handle
default/delete as a definition, but this is too late: when adding the
declaration, we already treated the declaration as "user-provided"
when in fact it was merely "user-declared".
