46925cc515 Fix TimeValue::now() on Unix. 
TimeValue()::now().toEpochTime() is supposed to be the same as time(),
but it wasn't, because toEpoch subtracted PosixZeroTime, but now()
didn't add PosixZeroTime!
Add a unittest to check this works.

b47463f436 remove support for "NoSub" from regex. It seems like a minor optimization 
and makes the API more annoying.  Add a Regex::getNumMatches() method.

ae5a12200c Fix a compile failure introduced by r82675 on MinGW which doesn't have 
setenv().  This patch just disables the test rather than getting putenv() to
work.  Thanks to Sandeep Patel for reporting the problem.

a trivial unittest would have caught.  This revision also adds the trivial

   larger buffer size.

a78433a090 Make TypeBuilder's result depend on the LLVMContext it's passed. 
TypeBuilder was using a local static variable to cache its result. This made it
ignore changes in its LLVMContext argument and always return a type constructed
from the argument to the first call.

729d642928 Now that googletest can print ConstantRange, use EXPECT_EQ when testing for 
equality. Prefer EXPECT_EQ(foo, Full) over EXPECT_TRUE(foo.isFullSet()) because
the former will print out the contents of the constant range that failed.

98f201632e split raw_os_ostream out to its own header and implementation file. This 
means that raw_ostream no longer has to #include <iosfwd>.  Nothing in llvm
should use raw_os_ostream.h, but llvm-gcc and some unit tests do.

e58499843b Fix off-by-one in llvm::Format::print. 
- This also shortens the Format.h implementation, and uses the print buffer
   fully (it was wasting a character).

 - This manifested as llvm-test failures, because one side effect was that
   raw_ostream would write garbage '\x00' values into the output stream if it
   happened that the string was at the end of the buffer. This meant that grep
   would report 'Binary file matches', which meant the silly pattern matching
   llvm-test eventually does would fail. Cute. :)

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.

4c892c05ec Parameterize the BumpPtrAllocator over a slab allocator. It defaults to using 
malloc, so there should be no functional changes to other code.

These changes are necessary since I have plans to use this allocator in the JIT
memory manager, and it needs a special allocator.

I also added some tests which helped me pinpoint some bugs.

ec10fcbd04 Replace intersectWith with maximalIntersectWith. The latter guarantees that 
all values belonging to the intersection will belong to the resulting range.
The former was inconsistent about that point (either way is fine, just pick
one.) This is part of PR4545.

393d8b0a0c Begin the painful process of tearing apart the rat'ss nest that is Constants.cpp and ConstantFold.cpp. 
This involves temporarily hard wiring some parts to use the global context.  This isn't ideal, but it's
the only way I could figure out to make this process vaguely incremental.
