Add more prototypes in mach/proto/as Change "register i;" to "int i;" to so clang stops warning about implicit int. Use function prototypes so clang stops warning about implicitly declared functions.

/* comm2.y */
Use libc assert(); fix dependencies; unbreak isduo(). Switch from custom assert() to libc assert() in mach/proto/as. Continue to disable asserts if DEBUG == 0. This change found a problem in the build system; comm2.y was missing depedencies on comm0.h and comm1.h. Add the missing dependencies to the cppfile rule. Allow the dependencies by modifying cppfile in first/build.lua to act like cfile if t.dir is false. Now that comm2.y gets rebuilt, I must fix the wrong prototype of yyparse() in comm1.h. I got unlucky as induo() in comm5.c was reading beyond the end of the array. It found an operator "= " ('=' then space) in the garbage, so it returned a garbage token number, and "VAR = 123" became a syntax error. Unbreak induo() by terminating the array.

Add .data8 for 8-byte literal integers to the assembler. This takes literal integers, not expressions, because each machine defines its own valu_t for expressions, but valu_t can be too narrow for an 8-byte integer, and I don't want to change all the machines to use a wider valu_t. Instead, change how the assembler parses literal integers. Remove the NUMBER token and add a NUMBER8 token for an int64_t. The new .data8 pseudo emits all 8 bytes of the int64_t; expressions narrow the int64_t to a valu_t. Don't add any checks for integer overflow; expressions and .data* pseudos continue to ignore overflow when a number is too wide. This commit requires int64_t and uint64_t in the C compiler to build the assembler. The ACK's own C compiler doesn't have these. For the assembler's temporary file, add NUMBER4 to store 4-byte integers. NUMBER4 acts like NUMBER[0-3] and only stores a non-negative integer. Each negative integer now takes 8 bytes (up from 4) in the temporary file. Move the `\fI` and `\fP` in the uni_ass(6) manual, so the square brackets in `thing [, thing]*` are not italic. This looks nicer in my terminal, where italic text is underlined.
