In C99 signed shift (1 << 31) is undefined behavior, since the result
exceeds INT_MAX. Use 1U instead and move the shift after the check.

Consider the masking of PICSR and PICMR:
((cpu->env.picsr && (1 << i)) && (cpu->env.picmr && (1 << i)))
To correctly mask bits, we should use the bitwise AND "&" rather than
the logical AND "&&". Also, the loop is not necessary for masking.
Simply use (cpu->env.picsr & cpu->env.picmr).

clang warns that cpu_openrisc_load_kernel() can use 'entry' uninitialized:
hw/openrisc/openrisc_sim.c:69:9: error: variable 'entry' is used uninitialized
whenever '&&' condition is false [-Werror,-Wsometimes-uninitialized]
if (kernel_filename && !qtest_enabled()) {
^~~~~~~~~~~~~~~
hw/openrisc/openrisc_sim.c:91:19: note: uninitialized use occurs here
cpu->env.pc = entry;
^~~~~
Fix this by not attempting to change the CPU's starting PC unless
we actually loaded a kernel.

Many of these should be cleaned up with proper qdev-/QOM-ification.
Right now there are many catch-all headers in include/hw/ARCH depending
on cpu.h, and this makes it necessary to compile these files per-target.
However, fixing this does not belong in these patches.

Both fields are used in VMState, thus need to be moved together.
Explicitly zero them on reset since they were located before
breakpoints.
