b77c457cc8 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.

087d90e912 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.

Fix the help output so it fits on 80 cols.

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.
