7bf114c1bd Fix the root cause of the bootstrap failure:
There was no way to check if a given register/mode pair was valid. We now return
an error code (-2) instead of asserting. If anyone thinks that an assert
at this point  is really needed, we can autogen a hasValidDwarfRegNum instead.

804cb23305 [tablegen] A couple of changes to ClangDiagnosticEmmitter.
-Emit an empty warning option as string ("") instead of 0.
-For diagnostic names also emit the size of the string.

f415d8b646 Use a more efficient data structure for the "operand map". The number of
operands to an instruction aren't great, so an iterative search is fairly quick
and doesn't have the overhead of std::map.

the root if there is only one such node. This leaves only 2 verifier failures in

2a8eb722c7 In r131488 I misunderstood how VREV works. It splits the vector in half and splits each half. Therefore, the real problem was that we were using a VREV64 for a 4xi16, when we should have been using a VREV32.
Updated test case and reverted change to the PerfectShuffle Table.

c81c9709ef vrev is incorrectly defined in the perfect shuffle table. The ordering is backwards (should be 0x3210 versus 0x1032) which exposed a bug when doing a shuffle on a 4xi16. I've attached a test case.

6bfba2e5af Prefer cheap registers for busy live ranges.
On the x86-64 and thumb2 targets, some registers are more expensive to encode
than others in the same register class.

Add a CostPerUse field to the TableGen register description, and make it
available from TRI->getCostPerUse. This represents the cost of a REX prefix or a
32-bit instruction encoding required by choosing a high register.

Teach the greedy register allocator to prefer cheap registers for busy live
ranges (as indicated by spill weight).

202a7a1e3f Add a new bit that ImmLeaf's can opt into, which allows them to duck out of
the generated FastISel.  X86 doesn't need to generate code to match ADD16ri8 
since ADD16ri will do just fine.  This is a small codesize win in the generated
instruction selector.

1518afddea Implement major new fastisel functionality: the matcher can now handle immediates with
value constraints on them (when defined as ImmLeaf's).  This is particularly important
for X86-64, where almost all reg/imm instructions take a i64immSExt32 immediate operand,
which has a value constraint.  Before this patch we ended up iseling the examples into
such amazing code as:

	movabsq	$7, %rax
	imulq	%rax, %rdi
	movq	%rdi, %rax
	ret

now we produce:

	imulq	$7, %rdi, %rax
	ret

This dramatically shrinks the generated code at -O0 on x86-64.

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.

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.
