double interfaces where appropriate.
First bits of x86 long double constants handling

code. They should be rematerialized as move instructions.

The x86-64 ABI states that objects passed on the stack have
8 byte alignment. Implement that.

Patch by Sterling Stein!

llvm-svn: 41758

Use APFloat in UpgradeParser and AsmParser.
Change all references to ConstantFP to use the
APFloat interface rather than double.  Remove
the ConstantFP double interfaces.
Use APFloat functions for constant folding arithmetic
and comparisons.
(There are still way too many places APFloat is
just a wrapper around host float/double, but we're
getting there.)

Use APFloat interfaces for more references, mostly
of ConstantFPSDNode.

Comments added. It now generates V5TE multiply instructions. However, it is still necessary to model PUWLSH bits more clearly.

Added support to fold X86 load / store instructions. This allow rematerialized loads to be folded into their uses.

llvm-svn: 41599

Add a variant of foldMemoryOperand to fold any load / store, not just load / store from / to stack slots.

Add APFloat interfaces to ConstantFP, SelectionDAG.
Fix integer bit in double->APFloat conversion.
Convert LegalizeDAG to use APFloat interface in
ConstantFPSDNode uses.

in the trampoline lowering.  Lookup the jump and
mov opcodes for the trampoline rather than hard
coding them.

llvm-svn: 41577

Changed the stack frame layout, StackGrowsUp fits better to Mips strange stack.
Stack offset calculation bug fixed!
