Dan Gohman ca26f79051 Reapply r112091 and r111922, support for metadata linking, with a
fix: add a flag to MapValue and friends which indicates whether
any module-level mappings are being made. In the common case of
inlining, no module-level mappings are needed, so MapValue doesn't
need to examine non-function-local metadata, which can be very
expensive in the case of a large module with really deep metadata
(e.g. a large C++ program compiled with -g).

This flag is a little awkward; perhaps eventually it can be moved
into the ClonedCodeInfo class.

Owen Anderson 755aceb5d0 Don't use PassInfo* as a type identifier for passes. Instead, use the address of the static
ID member as the sole unique type identifier.  Clean up APIs related to this change.

Devang Patel 0dc3c2d37e Use ValueMap instead of DenseMap.
The ValueMapper used by various cloning utility maps MDNodes also.

present in the module.

Sanjiv Gupta 7828ff9535 Currently in LLVM, names of libcalls are assigned during TargetLowering
object construction. There is no provision to change them when the 
code for a function generated. 
So we have to change these names while printing assembly.

Sanjiv Gupta 84a85fcb91 Initial implementation of PIC16 Cloner pass.
This pass is supposed to be run on the linked .bc module.
It traveses the module call graph twice. Once starting from the main function
and marking each reached function as "ML". Again, starting from the ISR
and cloning any reachable function that was marked as "ML". After cloning
the function, it remaps all the call sites in IL functions to call the
cloned functions. 

Currently only marking is being done.

Chris Lattner 7ba0661f27 Stop building RTTI information for *most* llvm libraries. Notable
missing ones are libsupport, libsystem and libvmcore.  libvmcore is
currently blocked on bugpoint, which uses EH.  Once it stops using
EH, we can switch it off.

This #if 0's out 3 unit tests, because gtest requires RTTI information.
Suggestions welcome on how to fix this.

Sanjiv Gupta 47ea743618 Add a pass to overlay pic16 data sections for function frame and automatic
variables. This pass can be invoked by llvm-ld or opt to traverse over the call graph 
to detect what function frames and their automatic variables can be overlaid.
Currently this builds an archive , but needs to be changed to a loadable module.

leaf functions. This pass will be extended to color other nodes of the call tree 
as well in future.
