combine: More distribute_notes trouble (PR69737) · ec4836a7

PR64682 is a problem in distribute_notes, where it has trouble putting
a REG_DEAD note for a reg that is set twice in the right spot.  My fix
for that did the wrong thing for PR69567.  And then my attempted fix
for that one made PR64682 fail again.

Instead, let's just lose the note in such complicated cases, like we
already do in certain similar cases.


	PR rtl-optimization/64682
	PR rtl-optimization/69567
	PR rtl-optimization/69737
	* combine.c (distribute_notes) <REG_DEAD>: If the register is set
	in I2 as well, just lose it.

re PR go/66904 (cmd/go: "#cgo pkg-config:" comments do not work with gccgo) · 931f434a

	PR go/66904
    cmd/go: fix "#cgo pkg-config:" comments with gccgo
    
    Copy of https://golang.org/cl/18790 by Michael Hudson-Doyle.
    
    The unique difficulty of #cgo pkg-config is that the linker flags are recorded
    when the package is compiled but (obviously) must be used when the package is
    linked into an executable -- so the flags need to be stored on disk somewhere.
    As it happens cgo already writes out a _cgo_flags file: nothing uses it
    currently, but this change adds it to the lib$pkg.a file when compiling a
    package, reads it out when linking (and passes a version of the .a file with
    _cgo_flags stripped out of it to the linker). It's all fairly ugly but it works
    and I can't really think of any way of reducing the essential level of
    ugliness.
    
    Update golang/go#11739.
    GCC PR 66904.
