FreeBSD-specific porting work. cgo/libmach remain unimplemented. However, compilers, runtime, and packages are 100%. I still need to go through and implement missing syscalls (at least make sure they're all listed), but for all shipped functionality, this is done. Ship! ;) R=rsc, VenkateshSrinivas https://golang.org/cl/152142

runtime: use new #include "textflag.h" I did this just to clean things up, but it will be important when we drop the pkg directory later. LGTM=bradfitz R=r, bradfitz CC=golang-codereviews https://golang.org/cl/132600043

runtime: convert .s textflags from numbers to symbolic constants. Remove NOPROF/DUPOK from everything. Edits done with a script, except pclinetest.asm which depended on the DUPOK flag on main(). R=golang-dev, bradfitz CC=golang-dev https://golang.org/cl/12613044

runtime: unify amd64 -buildmode=exe entry point code All of the amd64 entry point code is the same except for Plan 9. Unify it all into asm_amd64.s.

// On FreeBSD argc/argv are passed in DI, not SP, so we can't use _rt0_amd64.

runtime: change amd64 startup convention Now the default startup is that the program begins at _rt0_amd64_$GOOS, which sets DI = argc, SI = argv and jumps to _rt0_amd64. This makes the _rt0_amd64 entry match the expected semantics for the standard C "main" function, which we can now provide for use when linking against a standard C library.

JMP runtime·rt0_go(SB)
runtime: unify amd64 -buildmode=c-archive/c-shared entry point code This adds the _lib entry point to various GOOS_amd64.s files. A future CL will enable c-archive/c-shared mode for those targets. As far as I can tell, the newosproc0 function in os_darwin.go was passing the wrong arguments to bsdthread_create. The newosproc0 function is never called in the current testsuite.
