Unify default construction of error_code uses on this idiom so that users don't
feel compelled to make static globals for naming convenience. (unfortunately I
couldn't make the original ctor private as some APIs don't return their result,
instead using an out parameter (that makes sense to default construct) - which
is a bit of a pity. I did, however, find/fix some cases of unnecessary default
construction of error_code before I hit the unfixable cases)

GlobalOpt runs early in the pipeline (before inlining) and complex class
hierarchies often introduce bitcasts or GEPs which weren't optimized away.
Teach it to ignore side-effect free instructions instead of depending on
other passes to remove them.

Flatten some of the arrays in the X86 disassembler tables to reduce space needed to store pointers on 64-bit hosts and reduce relocations needed at startup. Part of PR11953.

We were passing a decl to the consumer after all pending deserializations were finished
but this was not enough; due to processing by the consumer we may end up into yet another
deserialization process but the way FinishedDeserializing() was setup we would not ensure
that everything was fully deserialized before returning to the consumer.

Separate ASTReader::FinishedDeserializing() into two semantic actions.
The first is ensuring that a deserialization process ends up will fully deserialized decls/types even
if the process is started by the consumer.
The second is pushing "interesting" decls to the consumer; we make sure that we don't re-enter this
section recursively be checking a variable.

difference in the qual type. This is a workaround for the fact that
the type isn't artificial but the this decl is, however, we don't
have any way of representing it in the current metadata. For now,
however, just don't cache the full type.

Fixes rdar://10831526 and probably a couple of others.

user space programs. The core file support is implemented by making a process
plug-in that will dress up the threads and stack frames by using the core file
memory. 

Added many default implementations for the lldb_private::Process functions so
that plug-ins like the ProcessMachCore don't need to override many many 
functions only to have to return an error.

Added new virtual functions to the ObjectFile class for extracting the frozen
thread states that might be stored in object files. The default implementations
return no thread information, but any platforms that support core files that
contain frozen thread states (like mach-o) can make a module using the core
file and then extract the information. The object files can enumerate the 
threads and also provide the register state for each thread. Since each object
file knows how the thread registers are stored, they are responsible for 
creating a suitable register context that can be used by the core file threads.

Changed the process CreateInstace callbacks to return a shared pointer and
to also take an "const FileSpec *core_file" parameter to allow for core file
support. This will also allow for lldb_private::Process subclasses to be made
that could load crash logs. This should be possible on darwin where the crash
logs contain all of the stack frames for all of the threads, yet the crash
logs only contain the registers for the crashed thrad. It should also allow
some variables to be viewed for the thread that crashed.

calls to Decl::getASTContext() by Decl's methods will find the TranslationUnitDecl
