Fangrui Song 40a4cbb0f2 [MIR,test] Change llc -march=x86-64 to -mtriple=x86_64
Similar to 806761a762

-mtriple= specifies the full target triple while -march= merely sets the
architecture part of the default target triple (e.g. Windows, macOS).

Therefore, -march= is error-prone and not recommended for tests without
a target triple. The issue has been benign as these MIR tests do not
utilize object file format specific detail, but it's good to change
these tests to neighbor files that use -mtriple=x86_64
