[PATCH, gfortran testsuite]: Do not generate denormals in gfortran.dg/boz_9.f90

Hello!

It is not nice to upset FP hardware of various target architectures by generating denormalized single-precision FP numbers [1] in the testsuite. boz_9.f90 testcase fails on alpha due to alpha's somehow weird FP unit that requires software assistance to properly handle denormals. I believe that the test was not meant to check for various hardware oddities, so attached patch replaces denormals with some other otherwise sane meaningless floating-point values.

    * gfortran.dg/boz_9.f90: Do not generate denormal floating
    point numbers.  Remove -mieee option for alpha*-*-* targets.

Patch was tested on alphaev68-linux-gnu (with and without -mieee) and fixes:

FAIL: gfortran.dg/boz_9.f90  -O2  execution test
FAIL: gfortran.dg/boz_9.f90  -O3 -fomit-frame-pointer  execution test
FAIL: gfortran.dg/boz_9.f90  -O3 -fomit-frame-pointer -funroll-loops  execution test
FAIL: gfortran.dg/boz_9.f90  -O3 -fomit-frame-pointer -funroll-all-loops -finline-functions  execution test
FAIL: gfortran.dg/boz_9.f90  -O3 -g  execution test
FAIL: gfortran.dg/boz_9.f90  -Os  execution test


OK for mainline, 4.3 and 4.4 ?
