Change isnan() and isinf() to use a union to convert from double to
...
struct ieee_double, rather than a pointer cast. This seems to enable
GCC 2.95.3 to get the instruction dependencies right (the old one fell
foul of ANSI aliasing rules), and it also generates more sensible code in
general.
If this is the correct solution, it should be applied to the other ports.
If it's not, someone should come up with one that _is_ correct.

Create shared ARM source for libc, and move arm26 port over to using it.
...
The code is (almost) a direct copy of the current arm26 sources.
It's identical to the current arm32 sources, with the following exceptions:
- _C_LABEL is used on references to C labels from assembler.
- Function returns in assembler have APCS-26 versions in #ifdef __APCS_26__.
- It uses SoftFloat 2a rather than SoftFloat 1a.
The first two of these should be inconsequential. I believe that SoftFloat 2a
should work on arm32 and be backward-compatible with existing code, but this
is not obviously true. For now, arm32 remains using its own bits of libc.
