AArch64: Clean up CalleeSaveMethod frame and the use of temp registers. CalleeSaveMethod frame size changes : SaveAll : 368 -> 176 RefOnly : 176 -> 96 RefsAndArgs : 304 -> 224 JNI register spill size changes : 160 -> 88 In the transition assembly, use registers following the rules: 1. x0-x7 as temp/argument registers. 2. IP0, IP1 as scratch registers. 3. After correct type of callee-save-frame has been setup, all registers are scratch-able(probably except xSELF and xSUSPEND). 4. When restore callee-save-frame, IP0 and IP1 should be untouched. 5. From C to managed code, we assume all callee save register in AAPCS will be restored by managed code except x19(SUSPEND). In quick compiler: 1. Use IP0, IP1 as scratch register. 2. Use IP1 as hidden argument register(IP0 will be scratched by trampoline.) Change-Id: I05ed9d418b01b9e87218a7608536f57e7a286e4c

Move quick frame info to OatQuickMethodHeader. Rename OatMethodHeader to OatQuickMethodHeader, move frame info from OatMethodOffsets to OatQuickMethodHeader. Retrieve the info from other places for non-quick methods (portable compiled bytecode or jni stub, generic jni, runtime, abstract and proxy). This change has a libcore/ companion CL "Remove ArtMethod's quick fields for frame size and spills." https://android-review.googlesource.com/94164 Bug: 11767815 Change-Id: I0e31a7875d76732e1ec479c86b9b5ca01203507f
