Output UTF-8-encoded characters as identifier characters into assembly

This is a behaviour configurable in the MCAsmInfo. I've decided to turn
it on by default in (possibly optimistic) hopes that most assemblers are
reasonably sane. If this proves a problem, switching to default seems
reasonable.
I'm not sure if this is the opportune place to test, but it seemed good

ARM: Don't form a t2LDRi8 or t2STRi8 with an offset of zero.
The load/store optimizer splits LDRD/STRD into two instructions when the
register pairing doesn't work out. For negative offsets in Thumb2, it uses
t2STRi8 to do that. That's fine, except for the case when the offset is in
the range [-4,-1]. In that case, we'll also form a second t2STRi8 with
the original offset plus 4, resulting in a t2STRi8 with a non-negative
offset, which ends up as if it were an STRT, which is completely bogus.
Similarly for loads.

"_foo", referenced from:
_bar in bundle-elQN6d.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
The linker was told that the 'foo' in 'main' was 'internal' and had no uses, so
it was dead stripped.
Another situation is something like:
define void @foo() {
ret void
}
define void @bar() {
call asm volatile "call _foo" ...
ret void
}
The only use of 'foo' is inside of an inline ASM call. Since we don't look
inside those for uses of functions, we don't specify this as a "use."
Get around this by not invoking the 'internalize' pass by default. This is an
admitted hack for LTO correctness.
