rather than stepping beyond the bounds of an array.  It turned out that

The PIC reg (r30) needs to be saved whenever the prologue sets it up,
not just if it is used elsewhere in the function.  Without this patch
the prologue for such a function will modify r30 without saving it
first, leading to disaster back in its callers.  This happened in the
testsuite for -m32 libgfortran and libstdc++, bootstrapped with -mlra,
many hundred times.

shrink_wrap_one_built_in_call had both guard_bb and guard_bb0.
It looks like an earlier version of the pass may have updated
one of the variables in the while loop, but now they're just
two names for the same thing.

Tested on x86_64-linux-gnu, aarch64-linux-gnu and arm-linux-gnueabi.

	* tree-call-cdce.c (shrink_wrap_one_built_in_call): Remove
	guard_bb0 and use guard_bb throughout.
