dc961baaea arm/armv7-[a|r]: move fpu save/restore to assembly handler 
Save/Restore FPU registers in C environment is dangerous practive,
which cannot guarantee the compiler won't generate the assembly code
with float point registers, especially in interrupt handling

a98a599cb9 arm/cortex-[a|r]: IRQ Switch return should with shadow SPSR 
The SPSR is used to store the current value of the CPSR when an exception
is taken so that it can be restored after handling the exception.
Each exception handling mode can access its own SPSR.

User mode and System mode do not have an SPSR because they are not
exception handling modes.

7b9978883c arch/arm: optimize context switch speed 
The current context save implementation saves registers of each task
to xcp context, which is unnecessary because most of the arm registers are
already saved in the task stack, this commit replace the xcp context with
stack context to improve context switching performance and reduce the tcb
space occupation of tcb instance.
