c1840b3da2 First bit of support for the dwarf .loc directive. This patch updates the 
needed parsing for the .loc directive and saves the current info from that
into the context.  The next patch will take the current loc info after an
instruction is assembled and save that info into a vector for each section for
use to build the line number tables.  The patch after that will encode the info
from those vectors into the output file as the dwarf line tables.

a273442891 Move enabling the local stack allocation pass into the target where it belongs. 
For now it's still a command line option, but the interface to the generic
code doesn't need to know that.

05ea54e886 Use MapValue in the Linker instead of having a private function 
which does the same thing. This eliminates redundant code and
handles MDNodes better. MDNode linking still doesn't fully
work yet though.

1f1b865c40 MC/Parser: Accept leading dollar signs in identifiers. 
- Implemented by manually splicing the tokens. If this turns out to be
   problematically platform specific, a more elegant solution would be to
   implement some context dependent lexing support.

4ce307f963 MapValue support for MDNodes. This is similar to r109117, except 
that it avoids a lot of unnecessary cloning by avoiding remapping
MDNode cycles when none of the nodes in the cycle actually need to
be remapped. Also it uses the new temporary MDNode mechanism.

250eb005d9 Avoid O(n*m) complexity in StringRef::find_first(_not)_of(StringRef). 
- Cache used characters in a bitset to reduce memory overhead to just 32 bytes.
- On my core2 this code is faster except when the checked string was very short
  (smaller than the list of delimiters).

3157ef1c13 This is the first step towards refactoring the x86 vector shuffle code. The 
general idea here is to have a group of x86 target specific nodes which are
going to be selected during lowering and then directly matched in isel.

The commit includes the addition of those specific nodes and a *bunch* of
patterns, and incrementally we're going to switch between them and what we
have right now. Both the patterns and target specific nodes can change as
we move forward with this work.

55ae515f9d Create the new linker type "linker_private_weak_def_auto". 
It's similar to "linker_private_weak", but it's known that the address of the
object is not taken. For instance, functions that had an inline definition, but
the compiler decided not to inline it. Note, unlike linker_private and
linker_private_weak, linker_private_weak_def_auto may have only default
visibility.  The symbols are removed by the linker from the final linked image
(executable or dynamic library).

63241f79e6 If the target says that an extending load is not legal, regardless of whether 
it involves specific floating-point types, legalize should expand an
extending load to a non-extending load followed by a separate extend operation.
For example, we currently expand SEXTLOAD to EXTLOAD+SIGN_EXTEND_INREG (and
assert that EXTLOAD should always be supported).  Now we can expand that to
LOAD+SIGN_EXTEND.  This is needed to allow vector SIGN_EXTEND and ZERO_EXTEND
to be used for NEON.
