More constructor cleanup.

Move to a single constructor with a default argument and avoid
the check and nullification.

Remove unnecessary constructors as the default conversions will handle
all enumerated cases. Reformat the rest of the existing constructors to
match.

Replace with a "null" RAUW with an assert since we'd actually like
to assume we're replacing. Clarify comments.

[mips] Use pristine object file while processing relocations.

    Similar to ARM change r182800, dynamic linker will read bits/addends from
    the original object rather than from the object that might have been patched
    previously. For the purpose of relocations for MCJIT stubs on MIPS, we
    internally use otherwise unused MIPS relocations.
    
    The change also enables MCJIT unit tests for MIPS (EL/BE), and the following
    two tests now pass:
    
    - MCJITTest.return_global and
    - MCJITTest.multiple_functions.
    
    These issues have been tracked as Bug 16250.

    Patch by Petar Jovanovic.

Fix aliases for shrd/shld to handle Intel syntax properly. Also suppress them from being used by the asm printer.

Split generated asm mnemonic matching table into a separate table for each asm variant.

This removes the need to store the asm variant in each row of the single table that existed before. Shaves ~16K off the size of X86AsmParser.o.

allow tests to run on powerpc-darwin8 again, checking for __ppc__

Fix PR16687 where we were incorrectly promoting an alloca that had
pending speculation for a phi node. The problem here is that we were
using growth of the specluation set as an indicator of whether
speculation would occur, and if the phi node is already in the set we
don't see it grow. This is a symptom of the fact that this signal is
a total hack.

Unfortunately, I couldn't really come up with a non-hacky way of
signaling that promotion remains valid *after* speculation occurs, such
that we only speculate when all else looks good for promotion. In the
end, I went with at least a much more explicit approach of doing the
work of queuing inside the phi and select processing and setting
a preposterously named flag to convey that we're in the special state of
requiring speculating before promotion.

Thanks to Richard Trieu and Nick Lewycky for the excellent work reducing
a testcase for this from a pretty giant, nasty assert in a big
application. =] The testcase was excellent.
