Most targets were using offsetof(CPUFooState, breakpoints) to determine
how much of CPUFooState to clear on reset. Use the next field after
CPU_COMMON instead, if any, or sizeof(CPUFooState) otherwise.

The current ISA mode needs to be saved in bit 0 of the resume address.
If the current instruction happens to be in a branch delay slot, then
the address of the preceding jump instruction should be stored instead.
exception_resume_pc already does both of these tasks, so it is
made available and reused.
MIPS_HFLAG_BMASK in hflags is cleared, otherwise QEMU may treat the
first instruction of the signal handler as a delay slot instruction.

target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are

standards conformant hwaddr.

This change updates the CPU reset sequence to use a common piece of code
that figures out CPU state flags, fixing the problem with MIPS_HFLAG_COP1X
not being set where applicable that causes floating-point MADD family
instructions (and other instructions from the MIPS IV FP subset) to trap.
As compute_hflags is now shared between op_helper.c and translate.c, the
function is now moved to a common header. There are no changes to this
function.
The problem was seen with the 24Kf MIPS32r2 processor in user emulation.
The new approach prevents system and user emulation from diverging -- all
the hflags state is initialized in one place now.

In commit 1bba0dc932e8826a7d030df3767daf0bc339f9a2 cpu_reset()
was renamed to cpu_state_reset(), to allow introducing a new cpu_reset()
that would operate on QOM objects.
All callers have been updated except for one in target-mips, so drop all
implementations except for the one in target-mips and move the
declaration there until MIPSCPU reset can be fully QOM'ified.

When hw interrupt pending bits in CP0_Cause are set, the CPU should
see the hw interrupt line as active. The CPU may or may not take the
interrupt based on internal state (global irq mask etc) but the glue
logic shouldn't care.
This fixes MIPS external hw interrupts in combination with -icount.
