The original code is a big `if` and `else` which ends with `continue`
like this:

  if (cond) {
    ...
    // fall through
  } else {
    ...
    continue;
  }

This patch rewrites it with the following.

  if (!cond) {
    ...
    continue;
  }
  ...

I honestly do not understand this part of code as it is too tangled.
What I'm trying now is to carefully disentangle it by transforming
code without changing meaining to see if I can improve overall
readability.

"Parallel" is the most important aspect of the functions,
so we shouldn't omit that.

This will be used in the sanitizer test suite, which wants to use DWARF
line tables.

At some point we should reconsider how LLD handles the long section
names required by DWARF debug sections.

This is a shorthand for Config->Wordsize == 8. So this is not strictly
necessary but seems handy. "Is 64 bit?" is easier to read than "Is
wordsize 8 byte?"

LinkerScript used to be a template class, so we couldn't instantiate
that class in elf::link. We instantiated ScriptConfig class earlier
instead so that the linker script parser can store configurations to
the object.

Now that LinkerScript is not a template, it doesn't make sense to
separate ScriptConfig from LinkerScript. This patch merges them.

In doing so, clean up the MD5 interface a little.  Most
existing users only care about the lower 8 bytes of an MD5,
but for some users that care about the upper and lower,
there wasn't a good interface.  Furthermore, consumers
of the MD5 checksum were required to handle endianness
details on their own, so it seems reasonable to abstract
this into a nicer interface that just gives you the right
value.

The patch introduces two new relocations expressions R_MIPS_GOT_GP and
R_MIPS_GOT_GP_PC. The first one represents a current value of `_gp`
pointer and used to calculate relocations against the `__gnu_local_gp`
symbol. The second one represents the offset between the beginning of
the function and the `_gp` pointer's value.

There are two motivations for introducing new expressions:
- It's better to keep all non-trivial relocation calculations in the
  single place - `getRelocTargetVA` function.
- Relocations against both `_gp_disp` and `__gnu_local_gp` symbols
  depend on the `_gp` value. It's a magical value points to the "middle"
  of GOT. Now all relocations use a common `_gp` value. But in fact,
  under some conditions each input file might require its own `_gp`
  value. I'm going to implement it in the future patches. So it's
  better to make `MipsGotSection` responsible for calculation of
  the `_gp` value.
