3f134cfe5e edwards25519 - skip useless operations and duplicate lookup table 
Just some trivial changes; no functional changes.

Skip useless nul additions and multiplications and comptime the
basepoint multiples only once.

b498d26376 Allow Zig to be built with clang 11 and -Werror

1c8cd268be stage1: Fix asyncCall with non-abi-aligned arguments 
Make the code used to calculate the variable slot index into the frame
match what's done during the structure layout calculation.

Prevents a few nasty LLVM errors when such types are passed around.

51ffb0548d CMake: properly detect when to rebuild zig1.o 
This is andrewrk's patch from ziglang#6724 (rebased)

CMake: Fix dependency problem

I don't know whether the error was expected cmake behavior or a bug.
This change seems to fix the issue. See ziglang#6724 for details.

cmake: add the correct set of zig stage2 sources

9e1e91dafc std: Make windows.ReadFile allow short reads 
Make it behave like the read() wrapper for unix systems.

over sockets.

6624f9cd5c stage1: Fix generation of pass-by-value args in async fns 
The mismatch between the argument slot type in the frame structure and
the one used in the store operation made the generated code write
garbage over the nearby fields.

7d0c461b77 std.fs.path.dirname: return null when input path is root 
This intentionally diverges from the unix dirname command, as well as
Python and Node.js standard libraries, which all have this edge case
return the input path, unmodified. This is a footgun, and nobody should
have ever done it this way.

Even the man page contradicts the behavior. It says:
"strip last component from file name". Now consider, if you
remove the last item from an array of length 1, then you
have now an array of length 0. After you strip the last component, there
should be no components remaining. Clearly, returning the input parameter
unmodified in this case does not match the documented behavior. This is
my justification for taking a stand on this API design.

85665386c6 stage1: Fix comparison of unions containing zero-sized types 
The code tried to be too smart and skipped the equality (returning true)
if the payload type was zero-sized.
This optimization is completely wrong when the union payload is a
metatype!

67ea47babd Revert "update runtime safety test case - unsigned-signed vector cast" 
This reverts commit 663f0b399c5f4e2528a969fba6cd58d8f9784f5a.

The behavior appears to be inconsistent between running locally and on
the CI.

I suspect it could be based on what vector CPU features are available.

663f0b399c update runtime safety test case - unsigned-signed vector cast 
now it returns "integer cast truncated bits" instead of "attempt to cast
negative value to unsigned integer" which I think is correct.
