91e0e06670 Add support for printing loop structure information in asm comments. 
This definitely slows down asm output so put it under an -asm-exuberant
flag.

This information is useful when doing static analysis of performance
issues.

60887bf820 Add DEBUG_WITH_TYPE as a clean alternative to tweaking DEBUG_TYPE. 
This:
--
#undef DEBUG_TYPE
#define DEBUG_TYPE "foo"
DEBUG(...)
#undef DEBUG_TYPE
#define DEBUG_TYPE ""
--
becomes this:
--
DEBUG_WITH_TYPE("foo", ...)

36a6dfff07 Modifications to dyn_cast/cast to make them work for objects too, instead of only pointers. 
The use case is if you have a wrapper class:

class Base {
  void *Ptr;
public:
  Base() : Ptr(0) { }
  operator bool() const { return Ptr; }
.....
}

and sub-wrappers that have exactly the same size:

class Sub : public Base {
public:
....
static bool classof(const Base*);
}

and in the code you would do:

void f(Base b) {
  Sub sub = dyn_cast<Sub>(b);
  if (sub) {
    ....
  }
}

20848835bf To catch bugs like the one fixed in 
http://llvm.org/viewvc/llvm-project?view=rev&revision=78127, I'm changing the
ExecutionEngine's global mappings to hold AssertingVH<const GlobalValue>. That
way, if unregistering a mapping fails to actually unregister it, we'll get an
assert. Running the jit nightly tests didn't uncover any actual instances of
the problem.

This also uncovered the fact that AssertingVH<const X> didn't work, so I fixed
that too.

ba72f59923 Fix FindExecutable to use sys::Path::GetMainExecutable instead of 
just argv[0]. And remove the code for searching the current
working directory and for searching PATH; the point of FindExecutable
is not to find whatever version of the executable can be found by
searching around, but to find an executable that accompanies the
current executable.

Update the tools to use sys::Program::FindProgramByName when they
want PATH searching.

34d4b90554 Many of Daniel's fixes. 
I'm returning the number of bytes actually copied so that the client has some
warning when it reads past the end of the buffer.

I'm keeping the distinction between getByte() and getBytes() for now for
subclasses that use functions like ptrace() on Linux and only have a restricted
interface.  This makes their implementation easier, and subclasses can always
write a one-line implementation of readByte() that uses their custom 
readBytes().

555ef2f462 MemoryObject - Abstract base class for contiguous addressable memory. 
Necessary for cases in which the memory is in another process, in a
  file, or on a remote machine.

The primary use for this is the llvm-mc disassemblers, so that they
can be targeted at arbitrary objects, not just in-process memory.
