Clean up <sys/limits.h> a bit.
<sys/limits.h> shouldn't even exist, but leave it in for backwards
compatibility.
Everything that seems legit moves to <limits.h>, though it still seems
like a lot of that ought to come from the compiler instead (there's even
an angry rant in the clang header to that effect).
Unfortunately, we've long exposed [a copy and paste of] the contents
of <float.h> from <limits.h> and <sys/limits.h>. This patch preserves
that for backwards compatibility, but at least switches us over to
using the real <float.h> instead.

Abort harder.
Some PoS internal system can't cope with more than 4 stack frames,
so the fact that our abort(3) implementation takes 4 frames by itself
makes it useless.
Re-reading POSIX, it only says "behaves as if", so the previous
implementation chain wasn't mandatory and we can just go straight to
calling tgkill...
Before:
#00 pc
0000000000069be4 /system/lib64/libc.so (tgkill+8)
#01 pc
0000000000066d50 /system/lib64/libc.so (pthread_kill+64)

#03 pc
00000000000010e0 /system/xbin/crasher64 (main+88)
This is less useful on 32-bit ARM because there there's an extra trampoline
from an assembler abort(3) implementation, so you'll still only get one
meaningful stack frame. But every other architecture will now get two!
But wait!
It turns out that the assembler hack isn't needed any more. Here we are
unwinding just fine all the way through the 32-bit ARM crasher:
Before (with direct call to tgkill but still using the assembler):
#00 pc
00049e7c /system/lib/libc.so (tgkill+12)
#01 pc
00019c6f /system/lib/libc.so (__libc_android_abort+50)

#05 pc

#04 pc
00000b38 /system/xbin/crasher (_start+96)
(As you can see, the fact that we see __libc_init rather than main was true
with the assembler stub too, so that's not a regression even if it does seem
odd...)

Don't pack relocations in libc.so
Ic9125cc1bc4c9ba9eb20d030de72e3ce1fb86fa6 disabled relocation packing
in libc.so, but the flag was dropped when we switched to Android.bp
in Ib0ba2d28bff88483b505426ba61606da314e03ab.

versioner: cache -cc1 flags generated by the clang Driver.
Profiling showed that majority of time spent by versioner was being
spent in the x86 and x86_64 driver statting random files in /usr/lib,
looking for a toolchain. Hardcode a list of per-target flags which
correspond to a subset of the ones generated by clang, and use those
instead of calling out to Driver.

I accidentally broken the cortex-a53 because it directly includes files
from cortex-a15. Rather than revert that part, just copy over the files
