rework leading underscores tested on win32/64 to pass the tests when enabled - libtcc.c : let tcc define __leading_underscore if enabled tcc_add_symbol() : add _ automatically - tccelf.c : remove tcc_get_symbol_err(), find_c_sym() currently symbol length is limited to 256 in several places, so we can use a fixed local buffer for now as well. - win32/lib/crtinit.c : new file for init/fini - lib/*.S, tests7* : use __leading_underscore - bt-log.c: this file wont work relibaly if compiled with gcc

#ifdef __leading_underscore
# define _ "_"
macos: Fix asm-c-connect-test via some heavy-handed hackery in the ASM symbol handling in case C symbols get a leading underscore (but ASM symbols do not). But this is now like clang and GCC on Darwin work: asm symbols are undecorated, C symbols get a _ prepended, so to connect both some trickery is involved for the ASM symbols that don't have a _ prepended. They must be included in the C symbol table (because that's what we use to lookup also ASM labels), but they also must not disturb the normal C symbol (which don't have the _ prepended), so they need some mangling. A bit unsatisfying, but well. So, add asm-c-connect-test to the working ones for Darwin as well.

Fix some code suppression fallout Some more subtle issues with code suppression: - outputting asms but not their operand setup is broken - but global asms must always be output - statement expressions are transparent to code suppression - vtop can't be transformed from VT_CMP/VT_JMP when nocode_wanted Also remove .exe files from tests2 if they don't fail.
