"optimizeCompareInstr" converts compares (cmp/cmn) into plain sub/add

most instructions, but not all. Some instructions that don't set the flags
(e.g. sub with immediate) can set the SP, whereas the flag setting version uses
the same encoding for the "zero" register.
Update the code to also check for the return register before performing the
optimization to make sure that a cmp doesn't suddenly turn into a sub that sets
the stack pointer.

Fixed a broken test suite test after recent editline merges.
The problem is that editline currently is trying to be smart when we paste things into a terminal window. It detects that input is pending and multi-line input is accepted as long as there is anything pending.
So if you open lldb and paste the text between the quotes:
"command regex carp
s/^$/help/
carp
"
We still still be stuck in the "command regex" multi-line input reader as it will have all three lines:
"s/^$/help/
carp
"
The true fix for this is something Kate Stone will soon work on:
- multi-line input readers must opt into this paste/pending input feature ("expr" will opt into it, all other commands won't)
- If we are in a multi-line input reader that requests this and stuff is pasted, then it will do what it does today
- if we start in a IOHandler that doesn't need/want pending input and text is pasted, and we transistion to a IOHandler that does want this functionality, then disable the pending input. Example text would be:
"frame variable
thread backtrace
expr
for (int i=0;i<10;++i)
(int)printf("i = %i\n", i);
frame select 0
"
When we push the expression multi-line reader we would disable the pending input because we had pending input _before_ we entered "expr".
If we did this first:
(lldb) expr
Then we pasted:
"void foo()
{
}
void bar()
{
}
"
Then we would allow the pending input to not look for an empty line to terminate the expression. We filed radar
19008425 to track fixing this issue.

Make DiagnosticsEngine::takeClient return std::unique_ptr<>. Updated
callers to store conditional ownership using a pair of pointer and unique_ptr
instead of a pointer + bool. Updated code that temporarily registers clients to
use the non-owning registration (+ removed extra calls to takeClient).

Handle use of default member initializers before end of outermost class
Specifically, when we have this situation:
struct A {
template <typename T> struct B {
int m1 = sizeof(A);
};
B<int> m2;
};
We can't parse m1's initializer eagerly because we need A to be
complete. Therefore we wait until the end of A's class scope to parse
it. However, we can trigger instantiation of B before the end of A,
which will attempt to instantiate the field decls eagerly, and it would
build a bad field decl instantiation that said it had an initializer but
actually lacked one.
Fixed by deferring instantiation of default member initializers until
they are needed during constructor analysis. This addresses a long
standing FIXME in the code.
Fixes PR19195.

IR: Simplify uniquing for MDNode
Change uniquing from a `FoldingSet` to a `DenseSet` with custom
`DenseMapInfo`. Unfortunately, this doesn't save any memory, since
`DenseSet<T>` is a simple wrapper for `DenseMap<T, char>`, but I'll come
back to fix that later.
I used the name `GenericDenseMapInfo` to the custom `DenseMapInfo` since
I'll be splitting `MDNode` into two classes soon: `MDNodeFwdDecl` for
temporaries, and `GenericMDNode` for everything else.
I also added a non-debug-info reduced version of a type-uniquing test
that started failing on an earlier draft of this patch.

Disable Editline on Windows.
Editline does not work correctly on Windows. This goes back at
least to r208369, and as a result r210105 was submitted to disable
libedit at runtime on Windows.
More recently, r222163 was submitted which re-writes editline
entirely, but makes the situation even worse on Windows, to the
point that it doesn't even compile. While it would be easy to
fix the compilation failure, this patch simply stops compiling
Editline entirely on Windows, as the simple compilation fix would
still result in a broken use of select on Windows, and as such a
broken implementation of Editline.
Since Editline was already disabled to begin with on Windows, we
don't attempt to fix the compilation failure or the underlying
issues, and instead just disable it "even more".

[SimplifyCFG] Make the value type of the hole check bitmask a power-of-2.
When converting a switch to a lookup table we might have to generate a bitmaks

The type of this mask depends on the number of switch statements, which can

the size of the bitmask to next power-of-2 value when necessary.

Fixed more fallout from running the test suite remotely on iOS devices.
Fixed include:
- Change Platform::ResolveExecutable(...) to take a ModuleSpec instead of a FileSpec + ArchSpec to help resolve executables correctly when we have just a path + UUID (no arch).
- Add the ability to set the listener in SBLaunchInfo and SBAttachInfo in case you don't want to use the debugger as the default listener.
- Modified all places that use the SBLaunchInfo/SBAttachInfo and the internal ProcessLaunchInfo/ProcessAttachInfo to not take a listener as a parameter since it is in the launch/attach info now
- Load a module's sections by default when removing a module from a target. Since we create JIT modules for expressions and helper functions, we could end up with stale data in the section load list if a module was removed from the target as the section load list would still have entries for the unloaded module. Target now has the following functions to help unload all sections a single or multiple modules:
size_t
Target::UnloadModuleSections (const ModuleList &module_list);
size_t
Target::UnloadModuleSections (const lldb::ModuleSP &module_sp);
