413b2e7539 Use SequenceToOffsetTable to create instruction name table. Saves space particularly on X86 where AVX instructions just add a 'v' to the front of other instructions.

243018ffcf Emit the LLVM<->DWARF register mapping as a sorted table and use binary search to do the lookup.
This also avoids emitting the information twice, which led to code bloat. On i386-linux-Release+Asserts
with all targets built this change shaves a whopping 1.3 MB off clang. The number is probably exaggerated
by recent inliner changes but the methods were already enormous with the old inline cost computation.

The DWARF reg -> LLVM reg mapping doesn't seem to have holes in it, so it could be a simple lookup table.
I didn't implement that optimization yet to avoid potentially changing functionality.

There is still some duplication both in tablegen and the generated code that should be cleaned up eventually.

dd9a50196c Introduce Register Units: Give each leaf register a number.
First small step toward modeling multi-register multi-pressure. In the
future, register units can also be used to model liveness and
aliasing.

cef670a3a3 Rip out emission of the regIsInRegClass function for the asm printer.

0d4e2ea00e Reapply 153764 and 153761 with a fix.
Use an explicit comparator instead of the default.

The sets are sorted, but not using the default comparator. Hopefully,
this will unbreak the Linux builders.

them all in a single table and use a SequenceToOffsetTable to share
suffixes.

184440e808 Add a SequenceToOffsetTable to TableGen.
This is similar to the StringToOffsetTable we use to produce string
tables, but it can be used for other sequences than strings, and it
eliminates entries for suffixes.

cc85160672 Continue cleanup of LIT, getting rid of the remaining artifacts from dejagnu
* Removed test/lib/llvm.exp - it is no longer needed 
* Deleted the dg.exp reading code from test/lit.cfg. There are no dg.exp files
  left in the test suite so this code is no longer required. test/lit.cfg is
  now much shorter and clearer 
* Removed a lot of duplicate code in lit.local.cfg files that need access to
  the root configuration, by adding a "root" attribute to the TestingConfig
  object. This attribute is dynamically computed to provide the same
  information as was previously provided by the custom getRoot functions. 
* Documented the config.root attribute in docs/CommandGuide/lit.pod

d66b9a222b Revert r152105: "Use uint16_t to store indices into string table"
This patch limited the concatenated register names to 64K which meant
that the total number of registers was many times less than 64K.

If any compilers actually enforce the 64K limit on string literals, and
it turns out to be a problem, we should fix that problem by not using
long string literals.
