Use LLVM-style command line (instead of DMD-style)
Note: For a backward compatible interface, use the new bin/ldmd script. It
supports all old options while passing on anything it doesn't recognize.
Some changes caused by this:
* -debug and -version are now -d-debug and -d-version due to a conflict with
standard LLVM options.
* All "flag" options now allow an optional =true/=1/=false/=0 suffix.
* Some "hidden debug switches" starting with "--" were renamed because LLVM
doesn't care about the number of dashes, so they were conflicting with other
options (such as -c).
The new versions start with "-hidden-debug-" instead of "--"
* --help works, but has a non-zero exit code. This breaks some Tango scripts
which use it to test for compiler existence. See tango.patch.
Some changes not (directly) caused by this;
* (-enable/-disable)-FOO options are now available for pre- and postconditions.
* -march is used instead of -m (like other LLVM programs), but -m is an alias
for it.
* -defaultlib, -debuglib, -d-debug and -d-version allow comma-separated values.
The effect should be identical to specifying the same option multiple times.
I decided against allowing these for some other options because paths might
contain commas on some systems.
* -fPIC is removed in favor of the standard LLVM option -relocation-model=pic
Bug:
* If -run is specified as the last argument in DFLAGS, no error is generated.
(Not very serious IMHO)
