2bafe7353e Add an assert for NativeReferenceIvarsV1. 
The maximum number of references the file with NativeReferenceIvarsV1 can
contain is 65534. If a file larger than that is converted to Native format,
the conversion will fail without any error message. This caused a subtle bug
that the LLD would produce a broken executable only when input files contain
too many references.

This issue exists since the RoundTripNativeTest is introduced in r193585. Since
then, it seems that nobody have linked any program having more than 65534
relocations with the LLD. Otherwise we would have found it earlier.

12027e58e1 Use range-based for loop. 
end() was evaluated every time through a loop. This patch eliminates it.

0879c1e601 [Native] Fix fallback atoms when writing to Native file. 
There is no test as currently there is no call to the NativeWriter.

Future commits will add calls to the NativeWriter.

d17ba4bd4d [lld] handle typeZeroFill atoms in ELF/Native/YAML 
BSS atoms dont take any file space in the Input file. They are associated
with a contentType(typeZeroFill). Similiar zero fill types also exist which
have the same meaning in terms of occupying file space in the Input.

These atoms have to be handled seperately when writing to the
lld's intermediate file or the lld test infrastructure.

Also adds a test.

Also change some local variable names: "ti" -> "context" and
"_targetInfo" -> "_context".

8338716e8d [ARM] Remove isThumb() as it's not used and it's not in the right place. 
Architecture specific code should reside in architecture specific directory
not in Atom. Looks like there are no efforts being made at this moment to
support ARM, so let's remove it for now.

64afcb4c6b Move everything over to TargetInfo. 
I really would have liked to split this patch up, but it would greatly
complicate the lld-core and lld drivers having to deal with both
{Reader,Writer}Option and TargetInfo.

abb6981f68 Major refactoring: Remove Platform concept. In its place there are 
now Reader and Writer subclasses for each file format.  Each Reader and
Writer subclass defines an "options" class which controls how that Reader
or Writer operates.
