Div/rem instruction handelling just before ecall

[saqibsaeed-lm]

How div/rem instruction is handled in quasar core when it comes just before ecall (for test finishing)?
while no div_wren or cancel signal is raised for the correct result/data of these instructions

@saqibsaeed-lm I suggest adding a filler of 34 nop cycles to flush out the div/rem result before ending the test cc: @haroon-shafique . I remember swerv having a max limit of 34 for div i think.
