84b454d1a2 misched preparation: modularize schedule emission.
ScheduleDAG has nothing to do with how the instructions are scheduled.

d3c9d9447e Use uint16_t to store InstrNameIndices in MCInstrInfo. Add asserts to protect all 16-bit string table offsets. Also make sure the string to offset table string is not larger than 65536 characters since larger string literals aren't portable.

f8cde7388e Cache the sized-ness of struct types, once we reach the steady state of
"is sized". This prevents every query to isSized() from recursing over
every sub-type of a struct type. This could get *very* slow for
extremely deep nesting of structs, as in 177.mesa.

This change is a 45% speedup for 'opt -O2' of 177.mesa.linked.bc, and
likely a significant speedup for other cases as well. It even impacts
-O0 cases because so many part of the code try to check whether a type
is sized.

Thanks for the review from Nick Lewycky and Benjamin Kramer on IRC.

179bc7cb59 Switch to a C-style cast here to silence a brain-dead MSVC warning. It
complains about the truncation of a 64-bit constant to a 32-bit value
when size_t is 32-bits wide, but *only with static_cast*!!! The exact
signal that should *silence* such a warning, and in fact does silence it
with both GCC and Clang.

Anyways, this was causing grief for all the MSVC builds, so pointless
change made. Thanks to Nikola on IRC for confirming that this works.

ed7692a136 Replace the hashing functions on APInt and APFloat with overloads of the
new hash_value infrastructure, and replace their implementations using
hash_combine. This removes a complete copy of Jenkin's lookup3 hash
function (which is both significantly slower and lower quality than the
one implemented in hash_combine) along with a somewhat scary xor-only
hash function.

Now that APInt and APFloat can be passed directly to hash_combine,
simplify the rest of the LLVMContextImpl hashing to use the new
infrastructure.

dc62a90696 Make the hashing algorithm Endian neutral. This is a bit annoying, but
folks who know something about PPC tell me that the byte swap is crazy
fast and without this the bit mixture would actually be different. It
might not be worse, but I've not measured it and so I'd rather not trust
it. This way, the algorithm is identical on both endianness hosts. I'll
look into any performance issues etc stemming from this.

1c1448984d Simplify the pair optimization. Rather than using complex type traits,
just ensure that the number of bytes in the pair is the sum of the bytes
in each side of the pair. As long as thats true, there are no extra
bytes that might be padding.

Also add a few tests that previously would have slipped through the
checking. The more accurate checking mechanism catches these and ensures
they are handled conservatively correctly.

Thanks to Duncan for prodding me to do this right and more simply.

4d628e200f We really want to hash pairs of directly-hashable data as directly
hashable data. This matters when we have pair<T*, U*> as a key, which is
quite common in DenseMap, etc. To that end, we need to detect when this
is safe. The requirements on a generic std::pair<T, U> are:

1) Both T and U must satisfy the existing is_hashable_data trait. Note
   that this includes the requirement that T and U have no internal
   padding bits or other bits not contributing directly to equality.
2) The alignment constraints of std::pair<T, U> do not require padding
   between consecutive objects.
3) The alignment constraints of U and the size of T do not conspire to
   require padding between the first and second elements.

Grow two somewhat magical traits to detect this by forming a pod
structure and inspecting offset artifacts on it. Hopefully this won't
cause any compilers to panic.

Added and adjusted tests now that pairs, even nested pairs, are treated
as just sequences of data.

Thanks to Jeffrey Yasskin for helping me sort through this and reviewing
the somewhat subtle traits.

c7384cfc7a Add support for hashing pairs by delegating to each sub-object. There is
an open question of whether we can do better than this by treating pairs
as boring data containers and directly hashing the two subobjects. This
at least makes the API reasonable.

In order to make this change, I reorganized the header a bit. I lifted
the declarations of the hash_value functions up to the top of the header
with their doxygen comments as these are intended for users to interact
with. They shouldn't have to wade through implementation details. I then
defined them at the very end so that they could be defined in terms of
hash_combine or any other hashing infrastructure.

Added various pair-hashing unittests.

4166989f10 Remove the misguided extension here that reserved two special values in
the hash_code. I'm not sure what I was thinking here, the use cases for
special values are in the *keys*, not in the hashes of those keys.

We can always resurrect this if needed, or clients can accomplish the
same goal themselves. This makes the general case somewhat faster (~5
cycles faster on my machine) and smaller with less branching.
