"""Returns the result, a list of result.Result objects and message.
If either or both of component_regression and component_crash_revision is not
None, is is assumed that crashing_component_path and
crashing_component_repo_url are not None.
Args:
stacktrace_string: A string representing stacktrace.
build_type: The type of the job.
chrome_regression: A string, chrome regression from clusterfuzz, in format
'123456:123457'
component_regression: A string, component regression in the same format.
chrome_crash_revision: A crash revision of chrome, in string.
component_crash_revision: A crash revision of the component,
if component build.
crashing_component_path: A relative path of the crashing component, as in
DEPS file. For example, it would be 'src/v8' for
v8 and 'src/third_party/WebKit' for blink.
crashing_component_name: A name of the crashing component, such as v8.
crashing_component_repo_url: The URL of the crashing component's repo, as
shown in DEPS file. For example,
'https://chromium.googlesource.com/skia.git'
for skia.
Returns:
A list of result objects, along with the short description on where the
result is from.
