Previously, relocation offsets are recalculated for .eh_frame sections
inside the main loop, and that messed up the main loop. This patch
separates that logic into a dedicated class.

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;
  }
  ...

This requires collectign all symbols referenced in the linker script
and adding them to symbol table as undefined symbol.

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 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.

Patch moves Sections array to
InputFile (root class for input files).

It is the only file type that needs it.

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.

This continues detemplation process.

Detemplating MipsGotSection<ELFT> is helpfull because can
help to detemplate getRelocTargetVA. (one more change is required)
It opens road to detemplation of GotSection<ELFT> and probably
something else after that.

I don't foresee having to makes these functions any stricter or
