47ba295b06 Rewrite and hide longjmperror.
This shouldn't be public API, isn't supported on x86/x86_64, and it's
unlikely anyone would have actually seen the message before anyway.
Using __libc_fatal makes it much more likely to be seen.

Elliott Hughes
69f05d291d Fix the printf family for non-ASCII.
The bug here turned out to be that we hadn't increased the constant
corresponding to the maximum number of bytes in a character to match
our new implementation, so any character requiring more than a byte
in UTF-8 would break our printf family.

15a0456d0b Remove unnecessary instructions from x86/x86_64 syscalls.
__set_errno returns -1 exactly so that callers don't need to bother.
The other architectures were already taking advantage of this, but
no one had ever fixed x86 and x86_64.

aeb3016f81 Fix unwinding through x86-64 __bionic_clone.
x86-64 needs these CFI directives to stop unwinding here.
I've also cleaned up the assembler a little, and made x86 and x86-64
a little more alike.

40fca0f08b Removes index() from bionic.
This function has been removed from POSIX.

Unfortunately, we can't leave #define index(a, b) strchr((a), (b)) in its place
because defining a preprocessor macro for index() breaks a whole lot of code.

that's something we're going to have to fix.

  BM_unistd_getpid       10000000        209

15b91e92a0 Fix x86 cfi directives for syscalls.
The syscall generation always used 4 bytes for each push cfi directive.
However, the first push should always use an offset of 8 bytes, each
subsequent push after that is only 4 bytes though.
