9bfd5f3b22 introduce a new OpKind abstraction which wraps up operand flavors in a tidy little wrapper.
No functionality change.

a90dbc133f change OperandsSignature to use SmallVector<char> instead of std::vector<string>
since the strings are always exactly one character, and there are usually only 2-3 operands.

4447d6506c since the VT is fixed for a ImmLeaf, there is no reason to expose it to the matching code.

7ed1391ff6 now that predicates have a decent abstraction layer on them, introduce a new
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.

543790673c Rework our internal representation of node predicates to expose more
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.

602fc06817 1. merge fast-isel-shift-imm.ll into fast-isel-x86-64.ll
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.

58194307c1 build: Add support for a SHOW_DIAGNOSTICS build variable.
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.

42e31dfd4f fix PR9629 - We were lowering regexes like a{{b|c}}d into ab|cd, which
is substantially different than a(b|c)d.  Form the latter regex instead.
This found a few problems in the testsuite, which serves as its test.

44dcfd3625 Replace the old algorithm that emitted the "print the alias for an instruction"
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.
