PR 3681.
* staptree.h (struct vardecl): Add a literal 'init' member for the
initialization value of globals.
* staptree.cxx (vardecl::vardecl): Initialize 'init' to NULL.
(vardecl::print): Print global init value during pass-1 output.
* main.cxx (printscript): Print global init values during verbose
pass-2 output.
* parse.cxx (parser::parse_global): Set the initialization literal of
global vardecls.
* translate.cxx (var::init): Don't unconditionally override the value
of numeric globals when the module_param isn't used.
(c_unparser::emit_global_param): Write numeric module_params directly
into the global variable, as an int64_t instead of long.
(c_unparser::emit_global): Add initialization to global declarations.
Don't create a temp module_param long for numeric globals anymore.
runtime/
* runtime.h (param_set_int64_t, param_get_int64_t,
param_check_int64_t): New functions to allow taking module parameters
directly as int64_t values.
testsuite/
* systemtap.base/global_init.exp, systemtap.base/global_init.stp: New
test for checking the timeliness of global initialization.
