Implemented correct stack probing on mingw/cygwin for dynamic alloca's.
Also, fixed static case in presence of eax livin. This fixes PR331

PS: Why don't we still have push/pop instructions? :)

For PR1297:
Intrinsic functions might need to be generated (if they are overloaded) so
returning a const char* is no longer possible. Change getOperationName to
return a std::string instead.

Add the 'explicit' keyword to several constructors that accept one
argument that don't appear intended as implicit-conversion operators.

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

Introduce new UnarySDNode/BinarySDNode/TernarySDNode nodes, which coallocate
their operands with the node itself. This reduces malloc traffic for operand
lists. This reduces isel time on kc++ from 2.6164 to 2.5570s, about 2.3%.

Add a new SDNode ctor and InitOperands method. This allows the operands for
an SDNode to be allocated as part of the node itself, instead of being a
separate new[]'d object. Switch HandleSDNode, LoadSDNode, and StoreSDNode
to use this mechanism. This saves one heap allocation and free for each node
of this type that is allocated. This reduces isel time from 2.7638 to 2.6164s
on kc++, which is a 5.6% speedup.
