An #endif in the wrong place would cause compile failure on powerpcle.
Using bl instead of b doesn't cause runtime failures as you might think,
but does mess the processor branch prediction.
Clean up code to appease modern GCC compiler.
Fix PowerPC Darwin FDE encodings to use pcrel correctly.  Modernise the picbase labels.

Fix PowerPC Darwin FDE encodings to use pcrel correctly.  Modernise the picbase labels.
This separates the 32-bit sysv/linux/bsd code from the 64-bit linux
code, and makes it possible to link code compiled with different
options to those used to compile libffi.  For example, a
-mlong-double-128 libffi can be used with -mlong-double-64 code.

Using the return value area as a place to pass parameters wasn't such
a good idea, causing a failure of cls_ulonglong.c.  I didn't see this
when running the mainline gcc libffi testsuite because that version of
the test is inferior to the upstreamm libffi test.

Using NUM_FPR_ARG_REGISTERS rather than NUM_FPR_ARG_REGISTERS64 meant
that a parameter save area could be allocated before it was strictly
necessary.  Wrong but harmless.  Found when splitting apart ffi.c
into 32-bit and 64-bit support.
