We used to split the inlined-into block at (= after) the call, and then
remove the call from the first block to insert it in the second.
The removal may cause unnecessary and unrecoverable resetting of debug
insns: we do not generate debug temps for calls.
Avoid the remove-and-reinsert dance by splitting the block before the
call.

For movsf, order stores so the VSX stores occur before the GPR
store which encourages the register allocator to use a traditional
FPR instead of a GPR. For movsd, order the stores so that the GPR
store comes before the VSX stores to allow the power6 to work.
This is due to the power6 not having a 32-bit integer store
instruction from a FPR.

When a processor enters a fast interrupts handler, and duplicate
register banks are configured, the processor saves the user context by
saving the registers in the main register bank to these additional
registers in the duplicate register bank. In this fast interrupt
context, when you specify the rgf_banked_regs option,the compiler does
not save the registers duplicated in the additional register bank are
not saved.

The AUX_IRQ_CTRL register controls the behavior of automated register
save and restore or prologue and epilogue sequences during a non-fast
interrupt entry and exit, and context save and restore instructions.
A user passes to the compiler the configuration of the AUX_IRQ_CTRL
register via mirq-ctrl-saved option. This option, specifies
gneral-purposes registers that the processor saves/restores on
interrupt entry and exit, and it is only valid for ARC EM and ARC HS
cores.
