56e017306e Simplify our endian.h implementation.
We can rely on the compiler's builtins. Tested on arm, arm64, mips, x86,
and x86-64.

9fb536de97 Clean up the arm64 setjmp.
Note that this doesn't address the fact that we don't save/restore the
real-time signals. But it does let us pass the tests we currently fail.

1de2548c8e Switch aarch64 to __builtin_bswap16.
It generates the same code.

ee369fb319 Bring our <machine/endian.h> files back in sync.
They'd drifted slightly which led to a compilation error in toybox,
which was assuming pid_t was defined. arm and arm64 were picking it
up via <endian.h> but x86 wasn't.

9aea164457 Add IFUNC support for arm64 and IRELATIVE reloc
There are number of changes in the way IFUNC related relocations are done:
 1. IRELATIVE relocations are now supported for x86/x86_64 and arm64.
 2. IFUNC relocations are now relying on static linker to generate
    them in correct order - this removes necessety of additional
    relocation pass for ifuncs.
 3. Related to 2: rela?.dyn relocations are preformed before .plt ones.
 4. Ifunc are resolved on symbol lookup this approach allowed to avoid
    mprotect(PROT_WRITE) call on r-x program segments.

cb65cc3fb4 Clean up <machine/ieee.h>.
The upstream intention was for this to be architecture-dependent, but it's a
lot clearer if we just have one copy.

4bd97cee28 Switch to gdtoa.
This gives us a real strtold for LP64 and fixes various LP64
bugs.

02c78a3867 Reimplement isinf/isnan/fpclassify.
Also move isinf and isnan into libc like everyone else.

Also move fpclassify to libc like the BSDs (but unlike glibc). We need
this to be able to upgrade our float/double/long double parsing to gdtoa.

Also add some missing aliases. We now have all of:

  isnan, __isnan, isnanf, __isnanf, isnanl, __isnanl,
  isinf, __isinf, isinff, __isinff, isinfl, __isinfl,
  __fpclassify, __fpclassifyd, __fpclassifyf, __fpclassifyl.

851e68a240 Unify our assembler macros.
Our <machine/asm.h> files were modified from upstream, to the extent
that no architecture was actually using the upstream ENTRY or END macros,
assuming that architecture even had such a macro upstream. This patch moves
everyone to the same macros, with just a few tweaks remaining in the
<machine/asm.h> files, which no one should now use directly.

I've removed most of the unused cruft from the <machine/asm.h> files, though
there's still rather a lot in the mips/mips64 ones.

9afe2884c7 Kill <machine/_types.h>.
Most of <machine/_types.h> was either unused, wrong, or identical across
all 32-/64-bit architectures.

I'm not a huge fan of <sys/_types.h> either, but moving the bits we need
up into there is a step forward.
