When launching in the shell, make sure if you specify a relative path, and if the current working directory has a space in it, that we don't hose the shell invocation.

Currently if we launch with a relative path, we prepend the current working directory to the PATH using:

PATH=`cwd`:$PATH a.out ...

We needed to add quotes around the value for PATH to make sure if any paths in PATH contained spaces, that we don't hose the shell command. Now we do a:

PATH="`cwd`:$PATH" a.out ...

of the copy is a subregister def. The current code assumes that it can do a full
def of the destination register, but it is not checking that the def operand is
read-undef. It also doesn't clear the subregister index of the destination in
the new instruction to reflect the full subregister def.

These issues were found running 'make check' with my next commit that enables
rematerialization in more cases.

Since functions with internal linkage don't have language linkage, it is valid
to overload them:

extern "C" {
       static int foo();
       static int foo(int);
}

So we mangle them.

I added hasCLanguageLinkage while fixing some language linkage bugs some
time ago so that I wouldn't have to check all users of isExternC. It turned
out to be a much longer detour than expected, but this patch finally
merges the two again. The isExternC function now implements just the
standard notion of having C language linkage.

some cases where functions with no language linkage were being treated as having
C language linkage. In particular, don't warn in

extern "C" {
  static NonPod foo();
}

Since getLanguageLinkage checks the language linkage, the linkage computation
cannot use the language linkage. Break the loop by checking just the context
in the linkage computation.
