Each of the object formats use a different directive for selecting the constant
section. Use a macro to avoid the duplication across a number of files. Also
correct a small macro mismatch on the Windows case (HIDDEN_DIRECTIVE -> HIDDEN).

The .rodata directive was added on the IA-64 (Itanium) platform. The LLVM IAS
supports the .rodata on i386 and x86_64 as well. There is no reason to really
restrict compilation of the builtins to just clang. By explicitly indicating
that the data is meant to be pushed into the .rodata section via the .section
.rodata, the assembly is made compatible with clang and gcc (with GAS).
This will enable building these routines on the Linux buildbots via CMake.

Place constants into .rdata if targeting ELF or COFF/PE. This should be
functionally identical, however, the data would be placed into a different
section. This is purely a cleanup change.

Make the whitespace a bit more uniform in the various assembly routines. This
also makes the assembly files a bit more uniform on the ARM side by explicitly
stating that it is using the unified syntax and that the contents of the code is
in the text section (or segment). No functional change.

The .align statements in ARM assembly routines is actually meant to be a power
of 2 alignment (e.g. .align 2 == 4 byte alignment, not 2). Switch to using
.p2align. .p2align is guaranteed to be a power-of-two alignment always and much
more explicit.
The .align in the case of x86_64 is byte alignment, use .balign instead of
.align.
