path.

a0a834a2f2 restore ability to do comptime math 
until https://github.com/ziglang/zig/issues/6168 is implemented,
partially revert 0bd53dd2033c60d3446abfb83209237c6eb6c9e2
in order to restore the ability to use std.math in comptime functions.

28a9da8bfc stage2: implement while loops (bool condition) 
* introduce a dump() function on Module.Fn which helpfully prints to
   stderr the ZIR representation of a function (can be called before
   attempting to codegen it). This is a debugging tool.
 * implement x86 codegen for loops
 * liveness: fix analysis of conditional branches. The logic was buggy
   in a couple ways:
   - it never actually saved the results into the IR instruction (fixed now)
   - it incorrectly labeled operands as dying when their true death was
     after the conditional branch ended (fixed now)
 * zir rendering is enhanced to show liveness analysis results. this
   helps when debugging liveness analysis.
 * fix bug in zir rendering not numbering instructions correctly

std: lessThan and greaterThan between signed and unsigned 
It is a deviation from C, but I think we should consider making this the behavior
of the operators. See #2133

Replace @typeOf with @TypeOf in all zig source 
This change was mostly made with `zig fmt` and this also modified some whitespace. Note that in some files, `zig fmt` produced incorrect code, so the change was made manually.

std.math: remove constants that should be expressions 
All four of these can be represented in fewer characters with
expressions, which will be guaranteed to happen at compile-time, and
have the same or better precision.

The other math constants here which depend on function calls could be
similarly removed if and when #425 is solved. However I left them for
now since Zig does not eagerly evaluate functions with comptime parameters.
