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

Emit a proper error message when register allocators run out of registers. This can't be just an assertion, users can always write impossible inline assembly. Such an assembly statement should be included in the error message. llvm-svn: 131024

Better diagnostics when inline asm fails to allocate. asm.c:2:7: error: ran out of registers during register allocation asm(""::"r"(0), "r"(1), "r"(2), "r"(3), "r"(4), "r"(5), "r"(6), "r"(7), "r"(8), "r"(9)); ^ llvm-svn: 134310

; The register allocator must fail on this function.
Emit a better error when running out of registers on inline asm. The most likely case where this error happens is when the user specifies too many register operands. Don't make it look like an internal LLVM bug when we can see that the error is coming from an inline asm instruction. For other instructions we keep the "ran out of registers" error. llvm-svn: 192041
