Early CFG simplification can fold conditionals down to selects, which is often a good thing, but it can also
hide jump threading opportunities by turning control flow into data flow.  Run an early JumpThreading pass
(adds approximately an additional 1% to optimization time on SPEC), allowing it to get a shot at these cases
first.  Fixes <rdar://problem/8447345>.

UnreachableBlockElim could incorrectly return false when it had not modified the CFG, but HAD modified some PHI nodes.  Fixes PR8174.

Fix PR8247: JumpThreading can cause a block to become unreachable while still having predecessor, if it is part of a self-loop.
Because of this, we cannot use the Simplify* APIs, as they can assert-fail on unreachable code.  Since it's not easy to determine
if a given threading will cause a block to become unreachable, simply defer simplifying simplification to later InstCombine and/or
DCE passes.

Fix breakpoint id range testing to disallow ranges that specify breakpoint locations from
crossing major breakpoint boundaries (must be within a single breakpoint if specifying locations).

Add .* as a means of specifying all the breakpoint locations under a major breakpoint, e.g. "3.*"
means "all the breakpoint locations of breakpoint 3".

Fix error message to make more sense, if user attempts to specify a breakpoint command when there
isn't a target yet.

which require the use of the shifter-operand. This will be used to split
the ldr/str instructions such that those versions needing the shifter operand
can get a different scheduling itenerary, as in some cases, the use of the
shifter can cause different scheduling than the simpler forms.
