The function is used only to resolve arguments of lifetime

[flang] Fixes for RESHAPE()

I fixed an assert caused by passing an empty array as the source= argument to
RESHAPE().  In the process, I noticed that there were no tests for RESHAPE(),
so I wrote a test that covers all the description in 16.9.163.  In the process,
I made the error messages more consistent and descriptive.  I also changed the
test to see if a reference to an intrinsic function was a constant to say that
it is a constant if it's a refererence to an invalid intrinsic.  This avoids
emitting multiple messages for the same erroneous source.

Commit abf546dd4f8326b821244b67eaa79ada7757d877 by Jason Molenda
debguserver's type sniffer to only treat .app things that end in .app

On an iOS device, if debugserver is left to figure out how to launch
the binary provided, it looks at the filename to see if it contains
".app" and asks FrontBoard to launch it.  However, if this is actually
a command line app with the characters ".app" in the name, it would
end up trying to launch that via the FrontBoard calls even though it
needed to be launched via posix_spawn.  For instance, a command line
program called com.application.tester.

Jim suggested this patch where we only send binaries that end in ".app"
to FrontBoard.

Often debugsever is invoked with a --launch command line argument to
specify the launch method, and none of this code is hit in that

[SimpleLoopUnswitch] Drop make.implicit metadata in case of non-trivial unswitching

Non-trivial unswitching simply moves terminator being unswitch from the loop
up to the switch block. It also preserves all metadata that was there. It might not
be a correct thing to do for `make.implicit` metadata. Consider case:
for (...) {
  cond = // computed in loop
  if (cond) return X;
  if (p == null) throw_npe(); !make implicit
Before the unswitching, if `p` is null and we reach this check, we are guaranteed
to go to `throw_npe()` block. Now we unswitch on `p == null` condition:
if (p == null) !make implicit {
  for (...) {
    if (cond) return X;
} else {
  for (...) {
    if (cond) return X;
Now, following `true` branch of `p == null` does not always lead us to
`throw_npe()` because the loop has side exit. Now, if we run ImplicitNullCheck
pass on this code, it may end up making the unswitch condition implicit. This may
lead us to turning normal path to `return X` into signal-throwing path, which is
not efficient.

Note that this does not happen during trivial unswitch: it guarantees that we do not
have side exits before condition being unswitched.

This patch fixes this situation by unconditional dropping of `make.implicit` metadata
when we perform non-trivial unswitch. We could preserve it if we could prove that the
condition always executes. This can be done as a follow-up.

[SimpleLoopUnswitch] Preserve make.implicit in non-trivial unswitch if legal

We can preserve make.implicit metadata in the split block if it is
guaranteed that after following the branch we always reach the block
where processing of null case happens, which is equivalent to
"initial condition must execute if the loop is entered".
