[Patch, microblaze]: Add optimized lshrsi3

When barrel shifter is not present, the immediate value
is greater than #5 and optimization is -OS, the
compiler will generate shift operation using loop.

[Patch, microblaze]: Add INIT_PRIORITY support

Added TARGET_ASM_CONSTRUCTOR and TARGET_ASM_DESTRUCTOR macros.

These macros allows users to control the order of initialization
of objects defined at namespace scope with the init_priority
attribute by specifying a relative priority, a constant integral
expression currently bounded between 101 and 65535 inclusive.

Lower numbers indicate a higher priority.

[Patch, microblaze]: Add supervisory call support

A function can be executed in supervisory mode when a function
is declared with svc_handler attribute.

If a function with svc_handler is called, the processor switches
to supervisory mode and executes. After executing the function
it returns to normal mode.

Same feature can also be invoked with svc_table_handler attribute
but this attribute will accept a service ID, to be used for
calling the function.

[Patch, microblaze]: Fixed missing save of r18 in fast_interrupt.

Register 18 is used as a clobber register, and must be stored when
entering a fast_interrupt. Before this fix, register 18 was only
saved if it was used directly in the interrupt function.

However, if the fast_interrupt function called a function that used
r18, the register would not be saved, and thus be mangled
upon returning from the interrupt.
