Summary:  incomplete cash flush in libjit

Original Submission:  the function jit_flush_exec() asumes the given pointer to 
lay on cache line boundary but no check is done. If the passed pointer is in 
between the last fragnent of the passed block can stay not flushed.

Consider the following cache lines with 4 bytes each
o is the first byte in a cache line

oxxxoxxxoxxx
012301230123

if the passed address points to 3 with size of 2 the first byte will be flushed 
the second not.

The attached patch fixes this making no restriction on the address and the 
block size
