[RFA] xstormy16-tdep.c: Initialize temporary frame cache in xstormy16_skip_prologue()

[Kevin Buettner <kevinb@redhat.com>]

[Corinna requested that I resend this patch...]

The patch below clears the frame cache for the call to
xstormy16_analyze_prologue().  If this initialization is not
performed, then the ``if (!cache.uses_fp)'' test following the call in
question will reference an uninitialized value.

Okay?

	* xstormy16-tdep.c (xstormy16_skip_prologue): Clear/initialize the
	frame cache.
