X87:  Make concrete classes for individual call descriptors

  Make concrete classes for individual call descriptors. The
  ic-convention classes that hold register specifications are
  merged into these new call descriptor classes, which should
  represent a final home for that information.

X87: CallDescriptors::InitializeForIsolate() is no longer needed.

original commit message:

  CallDescriptors::InitializeForIsolate() is no longer needed.

  CallInterfaceDescriptors initialize themselves lazily. Soon we can also tear
  down the CodeStubInterfaceDescriptor explicit initialization step.

Add cwd to all shell commands in auto roll scripts.

The v8 root directory is assumed to be the default cwd. All
commands executed in another directory (e.g. the chromium
checkout) need an explicit specification (also in the
tests).

This also fixes several small testing and robustness bugs:
- Get rid of all 'rm ...' shell calls
- Don't leak tmp files/dirs
- Add some forgotten shell calls to the test expectations
- Hardcode the DEPS location (must always be
chromium_dir/DEPS)
- Expect correct return code when terminating gracefully
