fpu: softfloat: drop INLINE macro

This commit expands all uses of the INLINE macro and drop it.

The reason for this is to avoid clashes with external libraries with
bad name conventions and also because renaming keywords is not a good
practice.

PS: I'm fine with this change to be licensed under softfloat-2a or
softfloat-2b.

softfloat: Fix shift128Right for shift counts 64..127

shift128Right would give the wrong result for a shift count
between 64 and 127. This was never noticed because all of
our uses of this function are guaranteed not to use shift
counts in this range.

softfloat: use GCC builtins to count the leading zeros

Softfloat has its own implementation to count the leading zeros. However
a lot of architectures have either a dedicated instruction or an
optimized to do that. When using GCC >= 3.4, this patch uses GCC builtins
instead of the handcoded implementation.

Note that I amware that QEMU_GNUC_PREREQ is defined in osdep.h and that
clz32() and clz64() are defined in host-utils.h, but I think it is better
to keep the softfloat implementation self contained.
