Adding Replacement serialization support
Adding a new data structure for storing the Replacements generated for a single
translation unit. Structure contains a vector of Replacements as well a field
indicating the main source file of the translation unit. An optional 'Context'
field allows for tools to provide any information they want about the context
the Replacements were generated in. This context is printed, for example, when
detecting conflicts during Replacement deduplication.
YAML serialization for this data structure is implemented in this patch. Tests
are included.

ARM: default to arm1176jzf-s for hard-float platforms.
It makes no sense to try and compile for arm7tdmi when we're targeting
something like gnueabihf. Although not strictly the most basic hardware
conceivable, I believe arm1176jzf-s is a reasonable compromise (that can always
be overridden explicitly if needed) since it's still in reasonably common use
unlike earlier cores.

Omit arguments of __builtin_object_size from the CFG.
This builtin does not actually evaluate its arguments for side effects,
so we shouldn't include them in the CFG. In the analyzer, rely on the
constant expression evaluator to get the proper semantics, at least for
now. (In the future, we could get ambitious and try to provide path-
sensitive size values.)
In theory, this does pose a problem for liveness analysis: a variable can
be used within the __builtin_object_size argument expression but not show
up as live. However, it is very unlikely that such a value would be used
to compute the object size and not used to access the object in some way.

[analyzer] Fix inefficiency in dead symbol removal
Summary:
ScanReachableSymbols uses a "visited" set to avoid scanning the same object
twice. However, it did not use the optimization for LazyCompoundVal objects,
which resulted in exponential complexity for long chains of temporary objects.
Adding this resulted in a decrease of analysis time from >3h to 3 seconds for
some files.

A partner to r188639, this is a somewhat heavy-handed fix to the general

There are other ways we could consider addressing this (see FIXME).
Possible minor reduction in debug info & avoid some cases where creating

created for, being created. (this is still possible with template
parameters - tests/fixes/improvements to follow)
