[Bug target/45373] New: V850 increment loops compile into incorrect assembly

[trap15 at raidenii dot net]

My machine is running 64bit Ubuntu, and GCC was configured with this line:
/opt/v850/gcc-4.4.4/configure --target=v850-elf --enable-targets=all
--prefix=/opt/v850 --disable-multilib --enable-languages=c --without-headers
--disable-nls --disable-threads --disable-shared --disable-libmudflap
--disable-libssp --disable-libgomp --disable-decimal-float
--enable-checking=release
The build command used is: v850-elf-gcc -nostdlib -nostartfiles -nodefaultlibs
-save-temps ctest.c -c -o ctest.v850.o
There were no warnings or other output

I built a bit of code containing a simple for loop that increments a number
from 0 to 8, and the assembly generated uses BLE for branching if the condition
is met. The proper instruction to generate would be BGE, since we want to run
the body of the code while 7 >= iterator, whereas it currently checks if 7 <=
iterator.
