Tom Weaver 7c781621f8 [dexter] Fix source-root-dir unittests on Windows
These tests were spuriously failing on Windows due to path separators getting
flipped from `/` to `\\`  in various parts of dexter:

test_add_breakpoint_with_source_root_dir
test_get_step_info
test_get_step_info_no_source_root_dir

Tested on Windows and Linux.

Patch written by @TWeaver.

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.
