Add nOS-V non-blocking scheduler server events
...
The events are emitted when we enter the scheduler with the non-blocking
flag, which is usually the case when using the nosv_yield and
nosv_schedpoint API functions.

Fix cast from pointer to integer in armv7
...
A pointer may not fit in a off_t type, so we first cast it to intptr_t
which must be able to hold it, then compute the diff which should fit in
a off_t and perform the cast.

Fix heap when size_t is not unsigned long long
...
When the width of size_t doesn't match the width of the unsigned long
long type, the number of leading zeros doesn't match, making the
heap_get_move() function return incorrect values. This is the case on
ARMv7 with 32 bits, where size_t is 32 bits but unsigned long long is 64
bits.
We check the size of size_t to select which builtin we need. The sizeof
operator cannot be used at preprocessing, so we rely on the
optimizations to only leave the proper assembly instruction.
