bef725be86 Use the new tool_output_file in several tools. This fixes a variety 
of problems with output files being left behind or output streams
being left unclosed. Fix llvm-mc to respect the -o option in all
modes, rather than hardcoding outs() in some cases.

d88735e805 Introduce a new tool_output_file class, which extends raw_ostream with 
functionality that most command-line tools need: ensuring that the
output file gets deleted if the tool is interrupted or encounters an
error.

3821009139 If the target says that an extending load is not legal, regardless of whether 
it involves specific floating-point types, legalize should expand an
extending load to a non-extending load followed by a separate extend operation.
For example, we currently expand SEXTLOAD to EXTLOAD+SIGN_EXTEND_INREG (and
assert that EXTLOAD should always be supported).  Now we can expand that to
LOAD+SIGN_EXTEND.  This is needed to allow vector SIGN_EXTEND and ZERO_EXTEND
to be used for NEON.

093ad188e7 CrashRecovery/Darwin: On Darwin, raise sends a signal to the main thread instead 
of the current thread. This has the unfortunate effect that assert() and abort()
will end up bypassing our crash recovery attempts. We work around this for
anything in the same linkage unit by just defining our own versions of the
assert handler and abort.

0498520f7c Update comment to remove special case for vector extending loads. An 
extending vector load should extend each element in the same way as the
corresponding scalar extending load.

7f2852ba2d When a set of bitmask operations, typically from a bitfield initialization, only modifies the low bytes of a value, 
we can narrow the store to only over-write the affected bytes.

c17025abdc Fix the msvc 2010 build. 
The Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 16.00.30319.01
implements parts of C++0x based on the draft standard. An old version of
the draft had a bug that makes std::pair<T1*, T2*>(something, 0) fail to
compile. This is because the template<class U, class V> pair(U&& x, V&& y)
constructor is selected, even though it later fails to implicitly convert
U and V to frist_type and second_type.

This has been fixed in n3090, but it seems that Microsoft is not going to
update msvc.
