Joseph Myers c535d68755 target/i386: fix fscale handling of rounding precision
The fscale implementation uses floatx80_scalbn for the final scaling
operation.  floatx80_scalbn ends up rounding the result using the
dynamic rounding precision configured for the FPU.  But only a limited
set of x87 floating-point instructions are supposed to respect the
dynamic rounding precision, and fscale is not in that set.  Fix the
implementation to save and restore the rounding precision around the
call to floatx80_scalbn.

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
