Richard Henderson 10dcb08b03 target/loongarch: Remove cpu_fcsr0 
All of the fpu operations are defined with TCG_CALL_NO_WG, but they
all modify FCSR0.  The most efficient way to fix this is to remove
cpu_fcsr0, and instead use explicit load and store operations for the
two instructions that manipulate that value.
