The fbstp implementation fails to check for out-of-range and invalid values, instead just taking the result of conversion to int64_t and storing its sign and low 18 decimal digits. Fix this by checking for an out-of-range result (invalid conversions always result in INT64_MAX or INT64_MIN from the softfloat code, which are large enough to be considered as out-of-range by this code) and storing the packed BCD indefinite encoding in that case.

These are i386 specific guest programs test-i386 --------- This program executes most of the 16 bit and 32 bit x86 instructions and generates a text output, for comparison with the output obtained with a real CPU or another emulator. The Linux system call modify_ldt() is used to create x86 selectors to test some 16 bit addressing and 32 bit with segmentation cases. The Linux system call vm86() is used to test vm86 emulation. Various exceptions are raised to test most of the x86 user space exception reporting. linux-test ---------- This program tests various Linux system calls. It is used to verify that the system call parameters are correctly converted between target and host CPUs. test-i386-fprem --------------- test-mmap --------- sha1 ---- hello-i386 ----------
