Summary:
This patch changes the way APInt is compared with a value of type uint64_t.
Before the uint64_t value was truncated to the size of APInt before comparison.
Now the comparison takes into account full 64-bit precision.
Test Plan: Unit tests added. No regressions. Self-hosted check-all done as well.

While often you want to use something specialized like StringMap, when
the strings already have persistent storage a normal densemap over them
can be more efficient.
This can't go into StringRef.h because of really obnoxious header chains
from the hashing code to the endian detection code to CPU feature
detection code to StringMap.

This commit moves the APSInt initialization code that's used by
the LLLexer class into a new APSInt constructor that constructs
APSInts from strings.
This change is useful for MIR Serialization, as it would allow
the MILexer class to use the same APSInt initialization as
LLexer when parsing immediate machine operands.

This allows us to match armv6m to default to thumb, but will also be used by
Clang's driver and remove the current incomplete copy in it.

Simplifying Triple::parseARMArch, leaving all the parsing to ARMTargetParser.
This commit also adds AArch64 detection to ARMTargetParser canonicalization,
and a two RedHat arch names (v{6,7}hl, meaning hard-float / little-endian).
Adding enough unit tests to cover the basics. Clang checks fine.

First ARMTargetParser FIXME, conservatively changing the way we parse CPUs
in the back-end. Still not perfect, with a lot of special cases, but moving
towards a more generic solution.
Moving all logic to the target parser made some unwritten assumptions
about architectures in Clang to break. I've added a lot of architectures
required by Clang, and default to CPUs that Clang believes it should
(and I agree).
I've also added a lot of unit tests, with the correct CPU for each
architecture, and Clang seems to be working correctly, too.
It also became clear that using "unsigned ID" as the argument for the get
methods makes it hard to know what ID, so I also changed the argument names
to match the enum type names.

Restructure Triple::getARMCPUForArch so that invalid values will
return nullptr, while retaining the behaviour that an argument
specifying no particular architecture version will give a default
CPU. This will be used by clang to give an error on invalid -march
values.
Also restructure the extraction of the architecture version from
the MArch string a little to hopefully make what it's doing clearer.

Summary: This patch fixes step D4 of Knuth's division algorithm implementation. Negative sign of the step result was not always detected due to incorrect "borrow" handling.
Test Plan: Unit test that reveals the bug included.

Summary:
When the arch is given as "arm" clang uses the default target CPU from
LLVM to determine what the real arch should be (i.e. "arm" becomes
"armv4t" because LLVM's getARMCPUForArch falls back to "arm7tdmi").
Default to "cortex-a8" so that we end up with "armv7" in clang.
the nacl-direct.c test in clang also covers this case.

APInt uses Knuth's D algorithm for long division. In rare cases the
implementation applied a transformation that was not needed.
Added unit tests for long division. KnuthDiv() procedure is fully covered.
There is a case in APInt::divide() that I believe is never used (marked with
a comment) as all users of divide() handle trivial cases earlier.

There doesn't seem to be any need to assert that iterator assignment is
between iterators over the same node - if you want to reuse an iterator
variable to iterate another node, that's perfectly acceptable. Just
don't mix comparisons between iterators into disjoint sequences, as
usual.

Without this, use of this copy ctor is deprecated in C++11 due to the
presence of a user-declared dtor.
Marking the class final is just a little extra security that there are
no further derived classes that may then end up using the intermediate
base class's copy assignment operator and cause slicing to occur.
I didn't bother marking the other (non-test) base class final, since it
has reference members so it won't have any implicit assignment operators
anyway. Open to ideas on that, though.
We probably want a warning about use of a slicing assignment operator,
then I wouldn't worry so much about marking the class as final.

With initializer lists there is a really neat idiomatic way to write
this, 'ArrayRef.equals({1, 2, 3, 4, 5})'. Remove the equal method which
always had a hard limit on the number of arguments. I considered
rewriting it with variadic templates but that's not really a good fit
for a function with homogeneous arguments.
'ArrayRef == {1, 2, 3, 4, 5}' would've been even more awesome, but C++11
doesn't allow init lists with binary operators.
