libgo: strip most C macros from runtime.inc
The Go runtime package is picking up C macros from runtime_sysinfo.go
and then re-exporting them to runtime.inc. This can cause name
conflicts. Change the Makefile so that we only put the macros we need
into runtime.inc. These are the constants that are actually defined by
Go code, not runtime_sysinfo.go. There are only a few, so we can
pattern match.
This is an additional hack on runtime.inc. The long term goal is to
convert the runtime package to Go and eliminate runtime.inc entirely, so
a few hacks seem acceptable.
Fixes GCC PR 77809.

runtime: copy internal locking code from Go 1.7 runtime
Remove the old locking code written in C.
Add a shell script mkrsysinfo.sh to generate the runtime_sysinfo.go
file, so that we can get Go copies of the system time structures and
other types.
Tweak the compiler so that when compiling the runtime package the
address operator does not cause local variables to escape. When the gc
compiler compiles the runtime, an escaping local variable is treated as
an error. We should implement that, instead of this change, when escape
analysis is turned on.
Tweak the compiler so that the generated C header does not include names
that start with an underscore followed by a non-upper-case letter,
except for the special cases of _defer and _panic. Otherwise we
translate C types to Go in runtime_sysinfo.go and then generate those Go
types back as C types in runtime.inc, which is useless and painful for
the C code.
Change entersyscall and friends to take a dummy argument, as the gc
versions do, to simplify calls from the shared code.

libgo: fix for runtime/check failure with "-O0 -g"
Tweak the makefile rules for the runtime/check test to
insure that the runtime package is compiled with
"-fgo-compiling-runtime". This resolves a test failure
(unsat on runtime.getcallerpc) when in a build directory where the
compiler flags have been configured to disable optimization.
