Richard Smith	3704eba1d1	D36604: PR34148: Do not assume we can use a copy relocation for an `external_weak` global ... An `external_weak` global may be intended to resolve as a null pointer if it's not defined, so it doesn't make sense to use a copy relocation for it.

Matthias Braun	6b898beb8e	X86: Do not use llc -march in tests. ... `llc -march` is problematic because it only switches the target architecture, but leaves the operating system unchanged. This occasionally leads to indeterministic tests because the OS from LLVM_DEFAULT_TARGET_TRIPLE is used. However we can simply always use `llc -mtriple` instead. This changes all the tests to do this to avoid people using -march when they copy and paste parts of tests.

Sriraman Tallam	f29fa586e1	New llc option pie-copy-relocations to optimize access to extern globals. ... This option indicates copy relocations support is available from the linker when building as PIE and allows accesses to extern globals to avoid the GOT.
