2019-05-08compiler: don't add pointer twice to value method of direct interface typeIan Lance Taylor2-10/+12
For a direct interface type T with a value method M, its pointer type (*T)'s method table includes a stub method of M which takes a (*T) as the receiver instead of a T. However, for the "typ" field of the method table entry, we added another layer of indirection, which makes it appear to take a **T, which is wrong. This causes problems when using reflect.Type.Method to get the method. This CL fixes the second, incorrect, indirection.

GCC revision 267634 implemented two_value_replacement function. However, a typo occurred during the parameter check, which caused us to miss some optimizations. The intent of the code might be to check that the input parameters are const int and their difference is one. However, when I read the code, I found that it is wrong to detect whether an input data plus one is equal to itself.

2019-05-07rs6000: Renumber the registersSegher Boessenkool5-188/+228
This renumbers the registers. It moves the VRs to 64..95, right after the GPRs and the FPRS. This means that the VSRs (which are aliases to the FPRs and the VRs, in that order) are consecutive now. It removes MQ, which has been just a stub for ages (it is a leftover from RIOS, old POWER). It moves the CR fields to 100..107, which is a bit easier to read than the 68..75 is was before. The rest fills the holes. It should be easy to move anything else after this series, so the exact order isn't very important anymore, we aren't stuck with it if we dislike it. Many things still want the GPRs to be at 0..31, and some things want the FPRs at 32..63. I don't think we'll ever want to change that, so I left it be. Small things... It removes DWARF_FRAME_REGISTERS, it used to save 1000 or so words of memory, but it has been just a handful for a while, and now it is one. Some whitespace fixes.
