[Qemu-devel] [PULL 5/7] fpu: Replace int8 typedef with int8_t

[Peter Maydell]

Replace the int8 softfloat-specific typedef with int8_t.
This change was made with

find include hw fpu target-* -name '*.[ch]' | xargs sed -i -e 
's/\bint8\b/int8_t/g'

together with manual removal of the typedef definition, and
manual undoing of various mis-hits.
