Tom Weaver b6d2212f52 [Dexter] Add support for Windows to regression test suite.
This patch addresses the issue of the regression suite not running on windows
hardware. It changes the following things:

* add new dexter regression suite command to lit.cfg.py that makes use of the
  clang-cl_vs2015 and dbgend builder and debuggers.

* sprinkle the new regressionsuite command through the feature and tool tests
  that require them.

* mark certain problem tests on windows

* [revert fix] fixed darwin regression test failures by adding unsupported line
  for system-darwin to command tests.

There's a couple of tests that fail (or pass) in unexpected ways on Windows.

Problem tests are both the penalty and perfect expect_watch_type.cpp tests.
Type information reporting parity is not possible a this time in dexter due to
the nature of how different debuggers report type information back to their users.

This is a collection of tests to check debugging information generated by 
compiler. This test suite can be checked out inside clang/test folder. This 
will enable 'make test' for clang to pick up these tests.

Some tests (in the 'llgdb-tests' directory) are written with debugger
commands and checks for the intended debugger output in the source file,
using DEBUGGER: and CHECK: as prefixes respectively.

For example::

  define i32 @f1(i32 %i) nounwind ssp {
  ; DEBUGGER: break f1
  ; DEBUGGER: r
  ; DEBUGGER: p i 
  ; CHECK: $1 = 42 
  entry:
  }

is a testcase where the debugger is asked to break at function 'f1' and 
print value of argument 'i'. The expected value of 'i' is 42 in this case.

Other tests are written for use with the 'Dexter' tool (in the 'dexter-tests'
and 'dexter' directories respectively). These use a domain specific language
in comments to describe the intended debugger experience in a more abstract
way than debugger commands. This allows for testing integration across
multiple debuggers from one input language.

For example::

  void __attribute__((noinline, optnone)) bar(int *test) {}
  int main() {
    int test;
    test = 23;
    bar(&test); // DexLabel('before_bar')
    return test; // DexLabel('after_bar')
  }

  // DexExpectWatchValue('test', '23', on_line='before_bar')
  // DexExpectWatchValue('test', '23', on_line='after_bar')

Labels two lines with the names 'before_bar' and 'after_bar', and records that
the 'test' variable is expected to have the value 23 on both of them.
