Hi,
This patch fixes arm pr45701 scan assembly tests. Those test register r3 being
used to maintain stack double word alignment. Recent optimizations reduced
number of local variables needed in those tests, removing necessity to push r3.
Testcase fixed by adding additional local variable.
Is patch OK?

* gcc.target/arm/pr45701-1.c (history_expand_line_internal): Add an
extra variable to force stack alignment.
* gcc.target/arm/pr45701-2.c (history_expand_line_internal): Add an
