no longer depends on Preprocessor, so we can move it out of Sema into
a nice new StringLiteral::getLocationOfByte method that can be used by
any AST client.

instructions have to distinguish between lists of single- and double-precision
registers in order for the ASM matcher to do a proper job. In all other
respects, a list of single- or double-precision registers are the same as a list
of GPR registers.

class, uses DominatorTree which is an analysis.  This change moves all of
the tricky hasConstantValue logic to SimplifyInstruction, and replaces it
with a very simple literal implementation.  I already taught users of
hasConstantValue that need tricky stuff to use SimplifyInstruction instead.
I didn't update InlineFunction because the IR looks like it might be in a
funky state at the point it calls hasConstantValue, which makes calling
SimplifyInstruction dangerous since it can in theory do a lot of tricky
reasoning.  This may be a pessimization, for example in the case where
all phi node operands are either undef or a fixed constant.

systematically, CollapsePhi will always return null here.  Note
that CollapsePhi did an extra check, isSafeReplacement, which
the SimplifyInstruction logic does not do.  I think that check
was bogus - I guess we will soon find out!  (It was originally
added in commit 41998 without a testcase).

with the Interrupted bit set.  Process::HandlePrivateEvent ignores Interrupted events.
DoHalt is changed to ensure that the stop even is processed, and an event with
the Interrupted event is posted.  Finally ClangFunction is rationalized to use this
facility so the that Halt is handled more deterministically.

Add a TestBase.getCompiler(self) method which returns the compiler in effect the

distinguish among different compilers.
