[bootstrap-O3] add a default initializer to avoid a warning at -O3
Building with the bootstrap-O3 configuration option fails to compile
input.c due to an AFAICT false-positive warning about an uninitialized
use of a variable.
This patch adds a default initializer to silence it.
for gcc/ChangeLog
* input.c (assert_char_at_range): Default-initialize
actual_range.
