cce738c9d5 Add mimalloc as a git submodule 
This change adds mimalloc as a git submodule so that `make` doesn't
try to clone mimalloc repo. This change should allow building mold
with the nix package manager, which doesn't provide network access
while building.

This change may conflict with a local `mimalloc` directory. If you
already have checked out mold and `mimalloc` directory exists in the
mold directory, you may need to remove it by `rm -r mimalloc` before
running `make`.

Requested by David Yamnitsky.

Fix string ctor param from strstr

Fix string ctor param from strstr 
When using the (begin, end) constructor for string, the types of begin
and end must match, including cv qualifiers. Depending on the library
headers used, strstr(const char *, const char *) can potentially return
char * or const char *, the former being a call to the C function strstr
and the latter being a call to C++ std::strstr.

This commit fixes the clang portion of issue #21, by explicitly casting
the return value of strstr to match the 1st param of the string ctor so
that the ctor can be instantiated regardless of the header used.

507ee38975 Set ELF header's p_paddr 
On Unix, p_paddr values (segment physical addresss) don't matter,
but GNU linkers set them to the same value as p_vaddr. We should
set the same values for compatibility with programs that make the
wrong assumption.

If all references to an DSO are weak, the DSO shouldn't be considered
being used in terms of --as-needed. This is needed for GNU ld compatibility.

This change is needed to build Gentoo's dev-lang/gprolog-1.4.5,
which is the GNU Forth package. GNU Forth creates ELF objects
itself, and it still uses .ctors and .dtors as opposed to .init_array
and .fini_array.
