Adds support for the R_X86_64_GOTPC32 relocation, which is a 32-bit delta to
the global offset table.

Since the delta to the GOT doesn't actually require any GOT entries to exist
this commit adds an extra fallback path to the getOrCreateGOTSymbol function:
If the symbol is in the extenal symbols list but no entry exists then the
symbol is turned into an absolute symbol pointing to an arbitrary address in
the current graph's allocation (accessing this address via the symbol would be
illegal, but any access should have triggered creation of a GOT entry which
would prevent this fallback path from being taken in the first place).

This commit also updates the llvm-jitlink tool to scrape the addresses of the
absolute symbols in the graph so that the testcase can see the now-absolute
_GLOBAL_OFFSET_TABLE_ symbol.

[clang-format] Handle Verilog assertions and loops

Assert statements in Verilog can optionally have an else part.  We
handle them like for `if` statements, except that an `if` statement in
the else part of an `assert` statement doesn't get merged with the
`else` keyword.  Like this:

    assert (x)
      $info();
    else
      if (y)
        $info();
      else if (z)
        $info();
      else
        $info();

`foreach` and `repeat` are now handled like for or while loops.

We used the type `TT_ConditionLParen` to mark the condition part so
they are handled in the same way as the condition part of an `if`
statement.  When the code being formatted is not in Verilog, it is
only set for `if` statements, not loops.  It's because loop conditions
are currently handled slightly differently, and existing behavior is
not supposed to change.  We formatted all files ending in `.cpp` and
`.h` in the repository with and without this change.  It showed that
setting the type for `if` statements doesn't change existing behavior.

And we noticed that we forgot to make the program print the list of
tokens when the number is not correct in `TokenAnnotatorTest`.  It's
fixed now.
