improve iplist comments. Switch iplist from allocating its sentinal object (for
...
end()) eagerly to allocating it lazily. This saves a lot of memory for JIT applications
that read a module but don't materialize most of the functions (e.g. 62K for 252.eon).

Fix PR1606:
...
The AC_CHECK_HEADER macro was used instead of AC_CHECK_HEADERS. The former does
not automatically add a #define to the configure variables while the latter
does. Consequently, the HAVE_PTHREAD_H symbol was not defined which caused the
Mutex.cpp file to compile to an empty implementation.

Fixed Sema::CheckEqualityOperands() and Sema::CheckRelationalOperands() to deal more
...
thoughtfully with incompatible pointers. This includes:
- Emit a diagnostic when two pointers aren't compatible!
- Promote one of the pointers/integers so we maintain the invariant expected by the
code generator (i.e. that the left/right types match).
- Upgrade the pointer/integer comparison diagnostic to include the types.

This adds a bunch of static functions that implement unsigned
...
two's complement bignum arithmetic. They could be used to
implement much of APInt, but the idea is they are enough to
implement APFloat as well, which the current APInt interface
is not suited for.

Improve error handling in the linker by:
...
1. Eliminate redundant error messages. LinkInFile and LinkInArchive
already call the error() method in each case so there's no use
telling the user again that an item couldn't be linked in.
2. Improve the formatting of error messages (separating content).
3. Change the wording for the warning about unrecognized files. Make
it clear that the file is being ignored.

If the source of a move is in spill slot, the reload may be folded to essentially a load from stack slot. It's ok to mark the stack slot value as available for reuse. But it should not be clobbered since the destination of the move is live.
