8874aaef1d Add a brief description for the tblgen program. More detail is needed but
the current author is not the person to provide it. Now that the file
exists, perhaps others will chime in and embellish.

12803f5b6b Major reorganization and extension of the code. The diff on this will be a
mess as functions were moved around into a better ordering. The code was
extended to provide various -gen-* options to better control what the
generated output should be. Currently it is possible to generate entire
modules (three different ways), functions, global variables, and types.

0b2375edfe Make the getNamedFunction and getNamedGlobal methods be const. They don't
change the module in any way and we should enforce that.

226368ff4e 1. No need to thwart this test with an environment variable. Turning it off
is the default and handled by the makefile system and runtest
2. Redirect stderr of llvm-as and llvm2cpp so that warning messages about
   instrinsics don't cause Tcl to report the run as failed.

15f7e01065 Fix more bugs. This version now passes all of the Feature test except for
a floating point conversion problem with NAN in intrinsics.ll. llvm2cpp
makes an attempt to provide the correct conversion, based on the
implementation in the CBackend writer, but it doesn't get NAN correct.

461bed2b75 Provide a simpler interface for getting a ConstantArray from a character
string. Instead of specifying the length, just specify whether the user
wants a terminating null or not. The default is "true" to retain the same
behavior as previously provided by this function.

8949477ae4 Adjust the interface to ConstantArray::get. The previous
implementation always added a null byte to the end of the string. It turns
out that this is not always wanted. By adding a length parameter we preserve
this behavior when length==0 (default value) but also allow other lengths
(not null terminated) to be created.
