Summary:
As discussed on lldb-dev, this patch moves some LLDB tests into a hierarchy that more closely
resembles the commands we use in the LLDB interpreter. This patch should only move tests
that use the command interpreter and shouldn't touch any tests that primarily test the SB API.

Summary:
While working on r370054, i've found it frustrating that the test output
was compeletely unhelpful in case of failures. Therefore I've decided to
improve that. In this I reuse the PExpectTest class, which was one of
our mechanisms for running pexpect tests, but which has gotten orhpaned
in the mean time.
I've replaced the existing send methods with a "expect" method, which
I've tried to design so that it has a similar interface to the expect
method in regular non-pexpect dotest tests (as it essentially does
something very similar). I've kept the ability to dump the transcript of
the pexpect communication to stdout in the "trace" mode, as that is a
very handy way to figure out what the test is doing. I've also removed
the "expect_string" method used in the existing tests -- I've found this
to be unhelpful because it hides the message that would be normally
displayed by the EOF exception. Although vebose, this message includes
some important information, like what strings we were searching for,
what were the last bits of lldb output, etc. I've also beefed up the
class to automatically disable the debug info test duplication, and
auto-skip tests when the host platform does not support pexpect.
This patch ports TestMultilineCompletion and TestIOHandlerCompletion to
the new class. It also deletes TestFormats as it is not testing anything
(definitely not formats) -- it was committed with the test code
commented out (r228207), and then the testing code was deleted in
r356000.

Summary:
Tab completing inside the multiline expression command can cause LLDB to crash. The easiest way
to do this is to go inside a frame with at least one local variable and then try to complete:
(lldb) expr
1. a[tab]
Reason for this was some mixup when we calculate the cursor position. Obviously we should calculate
the offset inside the string by doing 'end - start', but we are doing 'start - end' (which causes the offset to
become -1 which will lead to some out-of-bounds reading).
Fixes rdar://51754005
I don't see any way to test this as the *multiline* expression completion is completely untested at the moment
and I don't think we have any existing code for testing infrastructure for it.
