e7afdb2a42 Add RCBarriers to TargetInstrDesc. It's a list of register classes the given instruction can "clobber". For example, on x86 the call instruction can modify all of the XMM and fp stack registers.
TableGen has been taught to generate the lists from instruction definitions.

d748d12000 Keep track of *which* input constraint matches an output
constraint.  Reject asms where an output has multiple
input constraints tied to it.

1d0742a530 add an assert so that PR2356 explodes instead of running off an
array.  Improve some minor comments, refactor some helpers in
AsmOperandInfo.  No functionality change for valid code.

f1881095be Add comment on how tagged pointers are
distinguished from normal (untagged) ones
as per review comment.

I am sufficiently unaquainted with doxygen to
defer the markup to someone with more experience.

2fa8672ee6 Introduce a typing refinenement on tagged data
using the 'volatile' qualifier. This should not have any operational consequences
on code, because tags should always be stripped off (giving a non-volatile pointer)
before dereferencing. The new qualification is there to catch some attempts to use
tagged pointers in a context where an untagged pointer is appropriate.

Notably this approach does not catch dereferencing of tagged pointers, but helps
in separating the two concepts a bit.

cb8b4e9dd4 - Add target lowering hooks that specify which setcc conditions are illegal,
i.e. conditions that cannot be checked with a single instruction. For example,
SETONE and SETUEQ on x86.
- Teach legalizer to implement *illegal* setcc as a and / or of a number of
legal setcc nodes. For now, only implement FP conditions. e.g. SETONE is
implemented as SETO & SETNE, SETUEQ is SETUO | SETEQ.
- Move x86 target over.
