present.  Document this nonsense in langref.

1. Introduce some enums and accessors in the InlineAsm class
   that eliminate a ton of magic numbers when handling inline
   asm SDNode.
2. Add a new MDNodeSDNode selection dag node type that holds
   a MDNode (shocking!)
3. Add a new argument to ISD::INLINEASM nodes that hold !srcloc
   metadata, propagating it to the instruction emitter, which
   drops it.

No functionality change.

We would return the error without inserting the new instruction
into the program, so it wouldn't get deallocated, and an abort
would trigger when the module was deleted.

When a frame pointer is not otherwise required, and dynamic stack alignment
is necessary solely due to the spilling of a register with larger alignment
requirements than the default stack alignment, the frame pointer can be both
used as a general purpose register and a frame pointer. That goes poorly, for
obvious reasons. This patch brings back a bit of old logic for identifying
the use of such registers and conservatively reserves the frame pointer
during register allocation in such cases.

For now, implement for X86 only since it's 32-bit linux which is hitting this,
and we want a targeted fix for 2.7. As a follow-on, this will be expanded
to handle other targets, as theoretically the problem could arise elsewhere
as well.

A certain GDB testsuite case (local.cc) has a function nested inside a
class nested inside another function.  GCC presents the innermost
function to llvm-convert first.  Heretofore, the debug info mistakenly
placed the inner function at module scope.  This patch walks the GCC
context links and instantiates the outer class and function so the
debug info is properly nested.  Radar 7426545.
