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.

I'm going to hookize TARGET_FLT_EVAL_METHOD, so the current definition
of TARGET_FLT_EVAL_METHOD_NON_DEFAULT will stop working.
The relaxation enabled by TARGET_FLT_METHOD_NON_DEFAULT isn't portable,

TARGET_FLT_EVAL_METHOD_NON_DEFAULT in system.h to prevent future use.

Extend this attribute to cover long double ABIs, for 64-bit too.
This patch also corrects an error that crept in to code setting
rs6000_passes_float. See the added comment. Passing IEEE128 values

Tag_GNU_Power_ABI_Vector. Also adds a new option, default on, that
