Dan Gohman 3397bb248f Say "bytes" instead of "address units", since that's what the 
rest of LangRef uses.

Benjamin Kramer 736a4fc4fb BitcodeReader: Correctly insert blockaddress constant referring to a already parsed function. 
We inserted a placeholder that was never replaced because the function was
already visited. Assert that all placeholders have been resolved when tearing

Hans Wennborg 61b2ffa60f Make warnings about uninitialized fields include the field name. 
This makes the wording more informative, and consistent with the other
warnings about uninitialized variables.

Also, me and David who reviewed this couldn't figure out why we would
need to do a lookup to get the name of the variable; so just print the
name directly.

Sean Callanan 3e633a290e Fixed an oddity in the Objective-C class descriptors 
where the descriptor took a pointer to an object and
expected the Initialize function to dereference that
pointer and extract the isa value.  This caused one
of our tests to fail.

Greg Clayton 4b1b8b3e1d <rdar://problem/9959501> 
KDP -- now with rudimentary process control (continue only) and read + write registers (which means we can see stack frames) for x86_64, i386 and ARM.

Argyrios Kyrtzidis 6fa1682368 [PCH] After deserializing a DeclContext, if it has external lexical decls but not 
external visible decls, call DeclContext::setMustBuildLookupTable so that the
"lazy decls" bit of the LookupPtr is set.

Previously, in non-C++, if there were no new declarations causing the "lazy decls" bit
to be set, then DeclContext::lookups_begin() would fail to return the decls from the PCH.

Fixes rdar://12316296.
