ef484ab964 Fix an oversight: for modules with no other identifying target info, 
the sparc backend should be preferred when running on sparcs.

1eaba31f12 Add FastDSE, a new algorithm for doing dead store elimination. This algorithm is not as accurate 
as the current DSE, but it only a linear scan over each block, rather than quadratic.  Eventually
(once it has been improved somewhat), this will replace the current DSE.

NOTE: This has not yet been extensively tested.

629311ca52 Change the peep for EXTRACT_VECTOR_ELT of BUILD_PAIR to look for 
the new CONCAT_VECTORS node type instead, as that's what legalize
uses now. And add a peep for EXTRACT_VECTOR_ELT of INSERT_VECTOR_ELT.

47c93f0fe5 Simplify the handling of the --*flags options. The makefile already gets it 
right so there is no need to duplicate logic, just use the values the makefile
provides. 

Eliminate some redundnt -D options from the output.

Fix the help output so it fits on 80 cols.

00dacd0fa9 Makesure the -cppflags also uses the CPP.BaseFlags as the CPP.Defines only 
contains some of the defines but not all CPP flags.

60cb7070fe Make sure that preprocessor symbols like _DEBUG, NDEBUG, and _GLIBC_DEBUG are 
put into the CPP.Defines variable. Seems the convention was corrupted with
various changes made. It is important to get command line parameters into the
right variable because things like llvm-config and sub-makefiles depend on it.
