objects and populates them so we can test making expression calls with these
objects. We will need to make this test case more complete as time goes on to
make sure we can evaluate all functions.

member variables.
Modified lldb_private::Module to have an accessor that can be used to tell if
a module is a dynamic link editor (dyld) as there are functions in dyld on
darwin that mirror functions in libc (malloc, free, etc) that should not
be used when doing function lookups by name in expressions if there are more
than one match when looking up functions by name.

block-literal initializer expression causes IRgen to crash.
This patch fixes by saving it in StaticLocalDecl map
already used for such purposes. (radar 8390455).

The threshold value of 50 is arbitrary, and I chose it simply by analogy to the inlining thresholds, where
the baseline unrolling threshold is slightly smaller than the baseline inlining threshold. This could
undoubtedly use some tuning.

expressions correctly. These produced a result
variable with an initializer but no store
instruction, and the store instruction was as
a result never rewritten to become a store to a
persistent variable.
Now if the result variable has an initializer
but is never used, we generate a (redundant)
store instruction for it, which is then later
rewritten into a (useful) store to the persistent
result variable.

LiveIntervals already adds <imp-def> operands for super-registers when a subreg
def defines the whole register. Thus, it is not necessary to do it again when
rewriting.
In fact, the super-register imp-defs caused miscompilations because the late
scheduler couldn't see that the super-register was read.
We still add super-reg <imp-use,kill> operands when rewriting virtuals to
physicals.

register must be one of the destination registers for the load. Otherwise,
the tLDM instruction will write-back to the base register, which isn't what's
desired (otherwise, we'd have a t2LDM_UPD instead).

symbols with the same name and no debug information.
Also improved the way functions are called so we
don't automatically define them as variadic functions
in the IR.

(i.e., leave the value the same, so that a new
stack frame will be linked to the previous
stack) rather than zeroing out RBP.
This fixes calls to dlopen(), for example, which
does a backtrace to see which image is calling
it.

switch to using a ManagedStatic for the global PassRegistry instead of a
ManagedCleanup, and fix a destruction ordering bug this exposed.

turning (fptrunc (sqrt (fpext x))) -> (sqrtf x) is great, but we have
to delete the original sqrt as well. Not doing so causes us to do
two sqrt's when building with -fmath-errno (the default on linux).
