target/ppc: Set result to QNaN for DENBCD when VXCVI occurs
According to the ISA, for instruction DENBCD:
"If an invalid BCD digit or sign code is detected in the source
operand, an invalid-operation exception (VXCVI) occurs."
In the Invalid Operation Exception section, there is the situation:
"When Invalid Operation Exception is disabled (VE=0) and Invalid
Operation occurs (...) If the operation is an (...) or format the
target FPR is set to a Quiet NaN". This was not being done in
QEMU.
This patch sets the result to QNaN when the instruction DENBCD causes
an Invalid Operation Exception.
