  [clang][ARM] Remove non-existent arm1136jz-s CPU

There is an ARM1136JF-S and an ARM1136J-S but I could find
no references to an ARM1136JZ-S. In CPU manuals or the manual
for Arm Compiler 5.

See:
https://developer.arm.com/documentation/ddi0211/latest/
https://developer.arm.com/documentation/dui0472/latest/

Using this CPU you get:
$ ./bin/clang --target=arm-linux-gnueabihf -march=armv3m -mcpu=arm1136jz-s -c /tmp/test.c -o /tmp/test.o
'arm1136jz-s' is not a recognized processor for this target (ignoring processor)

Since the llvm target does not know what it is.

This is part of fixing https://bugs.llvm.org/show_bug.cgi?id=50454.
