Pavel Labath 12a7e6c09c dotest: improvements to the pexpect tests
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.

Raphael Isemann b0ca908808 [lldb][NFC] Move Clang-specific flags to ClangUserExpression
LLVMUserExpression doesn't use these variables and they are all specific to Clang.

Also removes m_const_object as this was actually never used by anyone (and Clang
didn't report it as we assigned it in the constructor which seems to count as use).

Jonas Devlieghere 86955ecd6a [lit] Print exit code in for unresolved (lldb)tests.
A test is marked unresolved when we're unable to find PASSED or FAILED
in the dotest output. Usually this is because we crashed and when that
happens the exit code can give a clue as to why. This patch adds the
exit code to the lit output to make it easier to investigate those
issues.

Jonas Devlieghere ff5982aa91 [test] Fix various module cache bugs and inconsistencies
Currently, lit tests don't set neither the module cache for building
inferiors nor the module cache used by lldb when running tests.
Furthermore, we have several places where we rely on the path to the
module cache being always the same, rather than passing the correct
value around. This makes it hard to specify a different module cache
path when debugging a a test.

This patch reworks how we determine and pass around the module cache
paths and fixes the omission on the lit side. It also adds a sanity
check to the lit and dotest suites.

Pavel Labath ef82098a80 Remove DWARFExpression::LocationListSize
Summary:
The only reason for this function's existance is so that we could pass
the correct size into the DWARFExpression constructor. However, there is
no harm in passing the entire data extractor into the DWARFExpression,
since the same code is performing the size determination as well as the
subsequent parse. So, if we get malformed input or there's a bug in the
parser, we'd compute the wrong size anyway.

Additionally, reducing the number of entry points into the location list
parsing machinery makes it easier to switch the llvm debug_loc(lists)
parsers.

While inside, I added a couple of tests for invalid location list
handling.

Jonas Devlieghere b543c16869 [dotest] Remove -q (quiet) flag.
This patch removes the -q (quiet) flag and changing the default
behavior. Currently the flag serves two purposes that are somewhat
contradictory, as illustrated by the difference between the argument
name (quiet) and the configuration flag (parsable). On the one hand it
reduces output, but on the other hand it prints more output, like the
result of individual tests. My proposal is to guard the extra output
behind the verbose flag and always print the individual test results.

Jonas Devlieghere 1fcdcd09bc [lit] Don't set DYLD_LIBRARY_PATH when DYLD_INSERT_LIBRARIES is set.
Setting DYLD_INSERT_LIBRARIES to the Asan runtime and DYLD_LIBRARY_PATH
to the LLVM shared library dir causes the test suite to crash with a
segfault. We see this on the LLDB sanitized bot [1] on GreenDragon. I've
spent some time investigating, but I'm not sure what's going on (yet).

Originally I thought this was because we were building compiler-rt and
were loading an incompatible, just-built Asan library. However, the
issue persists even without compiler-rt. It doesn't look like the Asan
runtime is opening any other libraries that might be found in LLVM's
shared library dir and talking to the team confirms that. Another
possible explanation is that we're loading lldb form a place we don't
expect, but that doesn't make sense either, because DYLD_LIBRARY_PATH is
always set without the crash. I tried different Python versions and
interpreters but the issue persist.

As a (temporary?) workaround I propose not setting DYLD_LIBRARY_PATH
when DYLD_INSERT_LIBRARIES is set so we can turn the Asan bot on again
and get useful results.
