MFC 275256:
Switch to the ARM unified assembly language as the clang integrated as only
supports it. Binutils supports it when the ".syntax unified" directive
is set.
Sponsored by: ABT Systems Ltd
MFC 275264:
Update _ENTRY to use _EENTRY to reduce the common code.
MFC 275321:
Remove extra labels, ENTRY_NP already provides them.

MFC 275322:
Correctly a few incorrect uses of ENTRY/EENTRY and END/EEND
Sponsored by: ABT Systems Ltd
MFC 275416:
Fix the name of the coprocessor to include the "p" prefix, the clang
integrated assembler expects this.
Sponsored by: ABT Systems Ltd
MFC 275418:
Switch to unified syntax so these can be built with clang 3.5.
Sponsored by: ABT Systems Ltd
MFC 275519:
Add missing END macros to some of the xscale functions.
Sponsored by: ABT Systems Ltd
MFC 275520:
Use the unified syntax in a few more assembly files
Sponsored by: ABT Systems Ltd
MFC 275521:
Set the alignment to 4-bytes after a string as clang 3.5 can switch to
thumb mode if this is incorrect.
Sponsored by: ABT Systems Ltd
MFC 275522:
Place the literal pool after a RET otherwise clang 3.5 tries to put it too
far away from a ldr psuedo instruction. With this clang will place the
literal value here where it's close enough to be loaded.

MFC 275523:
Switch to an armv6k cpu, without this clang 3.5 complains "bx lr" is
unsupported as it needs a newer cpu.
Sponsored by: ABT Systems Ltd
MFC 275524:
Switch to a .cpu directive. These will work when clang 3.5 is imported
where the .arch directive is a nop.

In ARM asm code, ensure that every ENTRY(foo) has a matching END(foo).
The EABI unwind info requires a .fnend for every .fnstart, and newer
binutils will complain about seeing two .fnstart in a row. This change
allows newer tools to compile our code.
Do not generate unwind info in asm functions if _STANDALONE is defined.
The .fnend op causes the assembler to emit RELOC references to unwind
support functions that don't exist in libstand.

As I looked through the C library, I noticed the FreeBSD MIPS port has a
hand-written version of index(). This is nice, if it weren't for the
fact that most applications call strchr() instead.
Also, on the other architectures index() and strchr() are identical,
meaning we have two identical pieces of code in the C library and
statically linked applications.
Solve this by naming the actual file strchr.[cS] and let it use
__strong_reference()/STRONG_ALIAS() to provide the index() routine. Do
the same for rindex()/strrchr().
This seems to make the C libraries and static binaries slightly smaller,
but this reduction in size seems negligible.

always perform substraction now, so no instruction could be rordered
to eliminate the conditional substraction.

main cycle only if the len passed is equal to 0. If end address
overflows use last possible address as the end address.

to if (len == 0).
The length is supposed to be unsigned, so len - 1 < 0 won't happen except
if len == 0 anyway, and it would return 0 when it shouldn't, if len was
> INT_MAX.

For setjmp() and longjmp(), put the signal mask where it's supposed to be,
instead of in the space reserved for fp regs.
