[X86] Regenerate TLS tests Use the correct check prefix for X86/X32/X64 target types. llvm-svn: 301092

; NOTE: Assertions have been autogenerated by utils/update_llc_test_checks.py
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. See also the discussion in https://reviews.llvm.org/D35287 llvm-svn: 309774

Teach LLVM about a PIE option which, when enabled on top of PIC, makes optimizations which are valid for position independent code being linked into a single executable, but not for such code being linked into a shared library. I discussed the design of this with Eric Christopher, and the decision was to support an optional bit rather than a completely separate relocation model. Fundamentally, this is still PIC relocation, its just that certain optimizations are only valid under a PIC relocation model when the resulting code won't be in a shared library. The simplest path to here is to expose a single bit option in the TargetOptions. If folks have different/better designs, I'm all ears. =] I've included the first optimization based upon this: changing TLS models to the *Exec models when PIE is enabled. This is the LLVM component of PR12380 and is all of the hard work. llvm-svn: 154294
