These functions semantically benefit from being inline; it makes sense
that `isInf(x)` where `x` is comptime-known should have a
comptime-known result.
* test/link: initial wasm support
This adds basic parsing and dumping of wasm section so they
can be tested using the new linker-test infrastructure.
* test/link: all wasm sections parsing and dumping
We now parse and dump all sections for the wasm binary format.
Currently, this only dumps the name of a custom section.
Later this should also dump symbol table, name, linking metadata and relocations.
All of those live within the custom sections.
* Add wasm linker test
This also fixes a parser mistake in reading the flags.
* test/link: implement linker tests wasm & fixes
Adds several test cases to test the wasm self-hosted linker.
This also introduces fixes that were caught during the implementation
of those tests.
* test-runner: obey omit_stage2 for standalone
When a standalone test requires stage2, but stage2 is omit
from the compiler, such test case will not be included as part
of the test suite that is being ran. This is to support CI's
where we omit stage2 to lower the memory usage.
Those 6 sets of square brackets are just a typographical aid used in this doc-comment, and must not actually be written by the user in their own format string... except for in one case where they must
* Avoid the implication that the numeric index is 1-based rather than 0-based
Starting with LLVM 14, the Libcalls to these functions are now lowered
using a Vec(2, u64) instead of the standard ABI for i128 integers, so
our compiler-rt implementation needs to be updated to expose the same
ABI on Windows.
Key blinding allows public keys to be augmented with a secret
scalar, making multiple signatures from the same signer unlinkable.

This is required by privacy-preserving applications such as Tor
onion services and the PrivacyPass protocol.
This accomplishes two things:
* Works around #8442 by putting stage1-specific logic in to disable all
the std.json tests.
* Slightly reduces installation size of zig since std lib files ending
in "test.zig" are excluded from being installed.
The fstype argument to the mount system call can be null. To see an
example run "strace -e trace=mount unshare -m":
```
mount("none", "/", NULL, MS_REC|MS_PRIVATE, NULL) = 0
...
```
The previous definition depends on a non-lang-spec-compliant memory
layout for packed structs, which happens to trigger #11989 in stage2.
This commit changes the struct to be an extern struct with an
align(4) field. However, stage1 cannot handle this, so conditional
compilation logic is used to select different struct definitions
depending on stage1 vs stage2.
This works around #11989 but does not solve the underlying problem -
putting an extern union inside a packed struct will still trigger the
assert.
After this, both stage1 and stage2 std lib tests run assertion-clean
with a debug LLVM 13.
Notable changes:
`_i386`, `_i486`, and `_i686` are renamed to `i386`, `i486`,
and `i686` respectively. `std.zig.fmtId` is enhanced to support
formatting `i386` as `@"i386"`.
Some CPU features which are actually CPU models have been
properly flattened, such as `apple_a12`, `apple_a13`, `apple_a7`,
`cortex_a78c`, `exynos_m4`, `neoverse_e1`, `neoverse_n1`,
`neoverse_n2`, `neoverse_v1`.
Some CPU features have been added and some have been removed, following
LLVM's lead.
CSky CPU features support is added.
