We don't need to repeat the template argument. They are not
ambiguous. MIPS is parameterized for ELFT, so we can't do this
for MIPS, though.

Now 'writer' creates an instance of `RuntimeFile` in the constructor, then
populates the file in the virtual function `addDefaultAtoms`, then pass
owning of this file to the caller of virtual function `createImplicitFiles`.
First, we do not need to keep an instance of `RuntimeFile` so long. It is
enough to create the file, right after that populate it and pass the owning.
Second, relationship between `createImplicitFiles` and `addDefaultAtoms`
is complicated. The `createImplicitFiles` might call `addDefaultAtoms`,
overridden version of `addDefaultAtoms` might call base class `addDefaultAtoms`,
and overridden version of `createImplicitFiles` might call base class
`createImplicitFiles` as well as `addDefaultAtoms`.
The patch solves both problems above. It creates and populates runtime files
right in the createImplicitFiles(), removes `addDefaultAtoms` at all and
does not keep references to runtime files in class fields.

All calls of findAbsoluteAtoms seem a bit awkward because of the type
of the function. It semantically returns a pointer to an AtomLayout or
nothing, so I made the function return AtomLayout*.
In this patch, I also expanded some "auto"s because their actual type
were not obvious in their contexts.

Puts symbols defined in linker script expressions in a runtime file that is
added as input to the resolver, making the input object files see symbols
defined in linker scripts.

The gotSymbol need not be a global static variable. Apart from this reason, This
variable was creating an issue with self hosting lld, as there seems to be an
issue running global initializers, when initializing the guard for this static
variable.
Program received signal SIGTRAP, Trace/breakpoint trap.

Handle resolution of symbols coming from linked object files lazily.
Add implementation of handling _GLOBAL_OFFSET_TABLE_ and __exidx_start/_end symbols for ARM platform.

Symbols addressing Thumb code have zero bit set in st_value to distinguish them from ARM instructions.
This caused wrong atoms' forming because of offset of one byte brought in by that corrected st_value.
Fixed reading of st_value & st_value-related things in ARMELFFile while forming atoms.
Symbol table generation is also fixed for Thumb atoms.

lldELF is used by each ELF backend. lldELF's ELFLinkingContext
also held a reference to each backend, creating a link-time
cycle. This patch moves the backend references to lldDriver.

The code is able to statically link the simplest case of:
int main() { return 0; }
* Only works with ARM code - no Thumb code, no interwork (-marm -mno-thumb-interwork)
* musl libc built with no interwork and no Thumb code
