target/ppc: Fix xvcmp* clearing FI bit
Vector instructions in general are not supposed to change the FI bit.
However, xvcmp* instructions are calling gen_helper_float_check_status,
which is leading to a cleared FI flag where it should be kept
unchanged.
As helper_float_check_status only affects inexact, overflow and
underflow, and the xvcmp* instructions don't change these flags, this
issue can be fixed by removing the call to helper_float_check_status.
By doing this, the FI bit in FPSCR will be preserved as expected.
Fixes: 00084a25adf ("target/ppc: introduce separate VSX_CMP macro for xvcmp* instructions")
