[ThinLTO] Compile time improvement to propagateAttributes
I found that propagateAttributes was ~23% of a thin link's run time
(almost 4x higher than the second hottest function). The main reason is
that it re-examines a global var each time it is referenced. This
becomes unnecessary once it is marked both non read only and non write
only. I added a set to avoid doing redundant work, which dropped the
runtime of that thin link by almost 15%.
I made a smaller efficiency improvement (no measurable impact) to skip
all summaries for a VI if the first copy is dead. I added an assert to
ensure that all copies are dead if any is. The code in
computeDeadSymbols marks all summaries for a VI as live. There is one
corner case where it was skipping marking an alias as live, that I
fixed. However, since the code earlier marked all copies of a preserved
GUID's VI as live, and each 'visit' marks all copies live, the only case
where this could make a difference is summaries that were marked live
when they were built initially, and that is only a few special compiler
generated symbols and inline assembly symbols, so it likely is never
provoked in practice.

[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;
throw_npe()
}
} 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.

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"
