[analyzer diagnostics] start prototyping stripping PathDiagnostics of unnecessary cruft caused by path inlining.
...
This introduces a concept of a "prunable" PathDiagnosticEvent. Currently this is a flag, but
we may evolve the concept to make this more dynamically inferred.

LegalizeIntegerTypes: Reenable the large shift with small amount optimization.
...
To avoid problems with zero shifts when getting the bits that move between words
we use a trick: first shift the by amount-1, then do another shift by one. When
amount is 0 (and size 32) we first shift by 31, then by one, instead of by 32.
Also fix a latent bug that emitted the low and high words in the wrong order
when shifting right.
Fixes PR12113.

Fix a bug in the code that builds SDNodes from vector GEPs.
...
When the GEP index is a vector of pointers, the code that calculated the size
of the element started from the vector type, and not the contained pointer type.
As a result, instead of looking at the data element pointed by the vector, this
code used the size of the vector. This works for 32bit members (on 32bit
systems), but not for other types. Added code to peel the vector type and
added a test.

Some ARM implementaions, e.g. A-series, does return stack prediction. That is,
...
the processor keeps a return addresses stack (RAS) which stores the address
and the instruction execution state of the instruction after a function-call
type branch instruction.
Calling a "noreturn" function with normal call instructions (e.g. bl) can
corrupt RAS and causes 100% return misprediction so LLVM should use a
unconditional branch instead. i.e.
mov lr, pc
b _foo
The "mov lr, pc" is issued in order to get proper backtrace.
