kind of predicate: one that is specific to imm nodes. The predicate function
specified here just checks an int64_t directly instead of messing around with
SDNode's. The virtue of this is that it means that fastisel and other things
can reason about these predicates.

structure and fix some fixmes. We now have a TreePredicateFn class
that handles all of the decoding of these things. This is an internal
cleanup that has no impact on the code generated by tblgen.

2. implement rdar://9289501 - fast isel should fold trivial multiplies to shifts
3. teach tblgen to handle shift immediates that are different sizes than the
shifted operands, eliminating some code from the X86 fast isel backend.
4. Have FastISel::SelectBinaryOp use (the poorly named) FastEmit_ri_ function
instead of FastEmit_ri to simplify code.

If enabled, this will attempt to use the CC_LOG_DIAGNOSTICS feature I dropped
into Clang to print a log of all the diagnostics generated during an individual
build (from the top-level). Not sure if this will actually be useful, but for
now it is handy for testing the option.

This found a few problems in the testsuite, which serves as its test.

with the newer, cleaner model. It uses the IAPrinter class to hold the
information that is needed to match an instruction with its alias. This also
takes into account the available features of the platform.
There is one bit of ugliness. The way the logic determines if a pattern is
unique is O(N**2), which is gross. But in reality, the number of items it's
checking against isn't large. So while it's N**2, it shouldn't be a massive time
sink.

- Also emit a list of packages and groups sorted by name
- Avoid iterating over DenseSet so that the output of the arrays is deterministic.

test cases for that.

According to A8.6.189 STM/STMIA/STMEA (Encoding T1), there's only tSTMIA_UPD available.
Ignore tSTMIA for the decoder emitter and add a test case for that.

Set the encoding bits to {0,?,?,0}, not 0. Plus delegate the disassembly of ADR to
the more generic ADDri/SUBri instructions, and add a test case for that.

This is a helper class that will make it easier to say which InstAliases can be
printed and which cannot (because of ambiguity).
