This matches GCC's documented (& actual) behavior. What Clang had implemented
as -Wswitch-enum was actually GCC's -Wswitch behavior. -Wswitch is on by
default (part of -Wall) and warns if a switch-over-enum, without a default
case, covers all enum values.

-Wswitch-enum, on the other hand, does not have the default clause and should
fire even in the presence of a default. This warning is off by default.

With this change the -Wswitch-enum flag is off-by-default in Clang but has no
functionality at the moment. I'll add that in a future commit.

Add __shim_type_info which fits below std::type_info and above all of the other type_info-derived classes.  This is where all of the virtual functions that serve as details of the inner-workings of type_info will live (safely hidden from public view).  All type_info objects will be safely down-castable to __shim_type_info, so as to access implementation detail virtual functions.  Also temporarily add some print/display statements to each type_info-derived class.  This is in support of the continuing development on the personality function.

Unfortunately I don't think there's a fix for this that will work upstream and
also satisfy Clang's -Wunreachable-code, which is a pity. But I'll give it some
more thought -perhaps there's some way out.

This warning acts as the complement to the main -Wswitch-enum warning (which
warns whenever a switch over enum without a default doesn't cover all values of
 the enum) & has been an an-doc coding convention in LLVM and Clang in my
experience. The purpose is to ensure there's never a "dead" default in a
switch-over-enum because this would hide future -Wswitch-enum errors.

The name warning has a separate flag name so it can be disabled but it's grouped
under -Wswitch-enum & is on-by-default because of this.

The existing violations of this rule in test cases have had the warning disabled
& I've added a specific test for the new behavior (many negative cases already
exist in the same test file - and none regressed - so I didn't add more).

A register mask operand kills any live physreg that isn't preserved.
Unlike an implicit-def operand, the clobbered physregs are never live
afterwards.

This means LiveVariables has to track a much smaller number of live
physregs, and it should spend much less time in addRegisterDead().
