Joseph Myers 374ff4d0a3 target/i386: fix fbstp handling of out-of-range values
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.
