helper_shilo has not been shifting an accumulator value correctly for negative
values in 'shift' field. Minor optimization for shift=0 case.
This change also adds tests that will trigger issue and check for regressions.

Content of register rs should be shifted for pos before applying a mask.
This change contains both fix for the instruction and to the existing test.

This is setting the stage for a cleanup of FPREM and FPREM1 helpers while being
sure that they behave same as bare metal.
The test constructs operands using combinations of corner cases for the
floating-point bitfields and prints operands, result and FPU status word for
FPREM and FPREM1. The outputs can then be compared between bare metal and QEMU.
The 'run-test-i386-fprem' make target does just that.

With i386-linux-user target on x86_64 host, this does not introduce any new test
failures.

This broke when the tests were moved from tests/ to tests/tcg/.
On x86_64 host/i386-linux-user non-kvm guest, test-i386 and test-mmap are broken, but at least they build.
To build/run the tests:
$ cd $BUILD_PATH/tests/tcg
$ SRC_PATH=path/to/qemu make <target>

These were identified using: http://github.com/lyda/misspell-check

-i option:
git ls-files|grep -vF .bin | misspellings -f - |grep -v '^ERROR:' |perl \

Manually eliding the FP, "rela->real" and resolving "addres" to
