0be6fe7139 continue pushing tblgen's support for nodes with multiple 
results forward.  We can now handle an instruction that 
produces one implicit def and one result instead of one or
the other when not at the root of the pattern.

5d3569e93c fix a bug in my recent patch that increased opcode size to 2 bytes: 
the index comments nested under OPC_SwitchOpcode were off by one.
This fixes the comments.

70feca409e Teach TableGen to understand X.Y notation in the TSFlagsFields strings. 
Remove much horribleness from X86InstrFormats as a result. Similar
simplifications are probably possible for other targets.

d5d5a3dcba Change tblgen to emit FOOISD opcode names as two 
bytes instead of one byte.  This is important because
we're running up to too many opcodes to fit in a byte
and it is aggrevated by FIRST_TARGET_MEMORY_OPCODE
making the numbering sparse.  This just bites the
bullet and bloats out the table.  In practice, this
increases the size of the x86 isel table from 74.5K
to 76K.  I think we'll cope :)

This fixes rdar://7791648

d1baa252c4 Fix evil TableGen bug in template parameters with defaults. 
If a TableGen class has an initializer expression containing an X.Y subexpression,
AND X depends on template parameters,
AND those template parameters have defaults,
AND some parameters with defaults are beyond position 1,
THEN parts of the initializer expression are evaluated prematurely with the default values when the first explicit template parameter is substituted, before the remaining explicit template parameters have been substituted.

32989deb96 Add support for XFAILing valgrind runs with memory leak checking independently 
of runs without leak checking.  We add -vg to the triple for non-checked runs,
or -vg_leak for checked runs.  Also use this to XFAIL the TableGen tests, since
tablegen leaks like a sieve.  This includes some valgrindArgs refactoring.

d734919465 major surgery on tblgen: generalize TreePatternNode 
to maintain a list of types (one for each result of

hacks added to emulate the old behavior in various
situations, but they can start disolving now.

2f36fe4380 Set numThreads to 1 by default when Python is older than 2.5.2.

Setting numThreads to 1 makes it slower, but at least the results reported are
correct.
