* config/mips/mips.h (STATIC_CHAIN_REGNUM): Remap to $15.
(FUNCTION_PROFILER): Save the static chain pointer into $2
beforehand and restore it aftewards.
(TRAMPOLINE_TEMPLATE): Adjust accordingly. Load the target
address directly into $25 and call the function through $25;
do not clobber $3. Pad the DImode version to cover the space
left by the deleted $25 <- $3 move.
(TRAMPOLINE_SIZE): Adjust the size of the SImode version after
the removal of the $25 <- $3 move.
(INITIALIZE_TRAMPOLINE): Update offsets accordingly.
* config/mips/sdemtk.h (FUNCTION_PROFILER): As for mips.h.
