-Missing CASA instruction handling for SPARC qemu-user
-Description of problem:
-Qemu-sparc does not handle the CASA instruction, even if the selected CPU (in this case, LEON3) support it.
-Steps to reproduce:
-1. Launch a program that use CASA instruction (any program, also "ls" on a recent glibc [>=2.31])
-2. qemu-sparc will raise "Illegal instruction"
-Additional information:
-The following patch remove the missing handling, but it needs asi load/store that is not implemented for sparc32 user-space.
