e86cee258c Merge remote-tracking branch 'origin/master' into stage2-whole-file-astgen 
In particular I wanted the change that makes `suspend;` illegal in the
parser.

9ac5f98200 std: Remove unneeded workaround 
Now that -% works on unsigned integers at comptime this (clever) hack is
not not needed anymore.

d5d0619aac stage2: ELF: avoid multiplication for ideal capacity 
ideal capacity is now determined by e.g.
x += x / f
rather than
x = x * b / a

This turns a multiplication into an addition, making it less likely to
overflow the integer. This commit also introduces padToIdeal() which
does saturating arithmetic so that no overflow is possible when
calculating ideal capacity.

ff14451b4a std: Implement more useful approxEq semantics 
Comparisons with absolute epsilons are usually useful when comparing
numbers to zero, for non-zero numbers it's advised to switch to relative
epsilons instead to obtain meaningful results (check [1] for more
details).

The new API introduces approxEqAbs and approxEqRel, where the former
aliases and deprecated the old `approxEq`, allowing the user to pick the
right tool for the job.

The documentation is meant to guide the user in the choice of the
correct alternative.

a0a834a2f2 restore ability to do comptime math 
until https://github.com/ziglang/zig/issues/6168 is implemented,
partially revert 0bd53dd203
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
