Anton Korobeynikov 20c9e4cbee Add new CC lowering rule: provide a list of registers, which can be 'shadowed',
when some another register is used for argument passing.
Currently is used on Win64.

Duncan Sands d97eea372a Introduce a new node for holding call argument
flags.  This is needed by the new legalize types
infrastructure which wants to expand the 64 bit
constants previously used to hold the flags on
32 bit machines.  There are two functional changes:
(1) in LowerArguments, if a parameter has the zext
attribute set then that is marked in the flags;
before it was being ignored; (2) PPC had some bogus
code for handling two word arguments when using the
ELF 32 ABI, which was hard to convert because of
the bogusness.  As suggested by the original author
(Nicolas Geoffray), I've disabled it for the moment.
Tested with "make check" and the Ada ACATS testsuite.

Evan Cheng 4d70ba3134 Rename CCIfStruct to CCIfByVal and CCStructAssign to CCPassByVal. Remove unused parameters of CCStructAssign and add size and alignment requirement info.

Duncan Sands e2287ed552 Eliminate the recently introduced CCAssignToStackABISizeAlign
in favour of teaching CCAssignToStack that size 0 and/or align
0 means to use the ABI values.  This seems a neater solution.
It is safe since no legal value type has size 0.

Dale Johannesen b988e7e8cd Add CCAssignToStackABISizeAlign for convenience in
dealing with types whose size & alignment are
different on different subtargets.  Use it for x86 f80.

still under discussion.

Chris Lattner 944200be45 If a function is vararg, never pass inreg arguments in registers. Thanks to

Anton Korobeynikov ed4b303c10 Refactoring of formal parameter flags. Enable properly use of
zext/sext/aext stuff.

Anton Korobeynikov e7ec3bc7bc Use new SDIselParamAttr enumeration. This removes "magick" constants
from formal attributes' flags processing.
