d5f075ed16 Compute the argument list as lazily as possible. This ensures that clients 
that don't use it don't have to pay the memory cost for the arguments.  This
allows us to avoid creating Argument nodes for many prototypes and for clients
who lazily deserialize code from a bytecode file.

790dceee30 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).

c1b981ab85 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.

9a05381a81 - If a dynamic_stackalloc alignment requirement is <= stack alignment, then the alignment argument is ignored. 
- *Always* round up the size of the allocation to multiples of stack
alignment to ensure the stack ptr is never left in an invalid state after a dynamic_stackalloc.

4c6c787315 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.

056b656f99 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.

f758fa5c35 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.
