Joseph Myers 9ecaf5ccec softfloat: fix floatx80 pseudo-denormal round to integer
The softfloat function floatx80_round_to_int incorrectly handles the
case of a pseudo-denormal where only the high bit of the significand
is set, ignoring that bit (treating the number as an exact zero)
rather than treating the number as an alternative representation of
+/- 2^-16382 (which may round to +/- 1 depending on the rounding mode)
as hardware does.  Fix this check (simplifying the code in the
process).

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
