Hi Jiradet
I've also reproduced the issue on my KBL (Intel® UHD Graphics 620) on Ubuntu
18.04 and 5.1.2 version of Kernel.
Also, I've checked that the issue isn't actual on 18.3.5 version of the mesa
and I bisected the issue:

 9dcf90d7ba966cba904266209087a87ea9c018b9 is the first bad commit
commit 9dcf90d7ba966cba904266209087a87ea9c018b9

intel/fs: Don't emit empty ELSE blocks.

While we can clean this up later, it's trivial to not generate the
stupid code in the first place, which saves some optimization work.
