Fully handle globals and functions in CGDebugInfo::getDeclarationOrDefinition()
Currently this function would return nothing for functions or globals that
haven't seen a definition yet. Make it return a forward declaration that will
get RAUWed with the definition if one is seen at a later point. The strategy
used to implement this is similar to what's done for types: the forward
declarations are stored in a vector and post processed upon finilization to
perform the required RAUWs.

this patch allows to emit correct imported declarations even in the absence of
an actual definition of the imported entity.

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.

Complete rewrite of interactive editing support for single- and multi-line input.
Improvements include:
* Use of libedit's wide character support, which is imperfect but a distinct improvement over ASCII-only
* Fallback for ASCII editing path
* Support for a "faint" prompt clearly distinguished from input
* Breaking lines and insert new lines in the middle of a batch by simply pressing return
* Joining lines with forward and backward character deletion
* Detection of paste to suppress automatic formatting and statement completion tests
* Correctly reformatting when lines grow or shrink to occupy different numbers of rows
* Saving multi-line history, and correctly preserving the "tip" of history during editing
* Displaying visible ^C and ^D indications when interrupting input or sending EOF
* Fledgling VI support for multi-line editing

Fixes for remote test suite execution of the "lldb/test/lang" directory.
Fixes include:
- Add a new lldbtest.TestBase function named registerSharedLibrariesWithTarget. This function can be called using the shared libraries for your test suite either as shared library basename ("foo"), path basename ("libfoo.dylib") or full path ("/tmp/lldb/test/lang/c/carp/libfoo.dylib"). These shared libraries are then registered with the target so they will be downloaded when the test is run remotely.
- Changed a lot of tests over to use SBDebugger::CreateTarget(...) calls instead of using "file a.out" commands.
- Cleaned up some tests to add new locations for breakpoints that all compilers should be able to abide by. Some tests and constants being loaded into values of structs and some compilers like arm64 will often combine two constant data loads into a single source line so some breakpoint locations were not being set correctly. Adding lines like 'puts("")' allow us to lock onto a source line that will have code.

[Thumb1] Re-write emitThumbRegPlusImmediate

miscompiled:

define void @test() {
%addr1.32 = alloca i8
%addr2.32 = alloca i32, i32 1028
call void @take_ptr(i8* %addr1)

This was emitting the following assembly to get the value of %addr1:
add r0, sp, #1020
add r0, r0, #8
However, "add r0, r0, #8" is not a valid Thumb1 instruction, and this
could not be assembled. The generated object file contained this,
resulting in r0 holding SP+8 rather tha SP+1028:
add r0, sp, #1020
add r0, sp, #8
This function looked like it could have caused miscompilations for
other combinations of registers and offsets (though I don't think it is
currently called with these), and the heuristic it used did not match
the emitted code in all cases.

- We pretended that import libraries were like any old COFF file, they
are not. In fact, they aren't really COFF files at all, we should

- Our symbol iterators were more than happy to attempt to go past the
end of the symbol table if you had a symbol with a bad list of
auxiliary symbols.
