ARM64: initial backend import This adds a second implementation of the AArch64 architecture to LLVM, accessible in parallel via the "arm64" triple. The plan over the coming weeks & months is to merge the two into a single backend, during which time thorough code review should naturally occur. Everything will be easier with the target in-tree though, hence this commit. llvm-svn: 205090

; Check that misuse of anyregcc results in a compile time error.
RegAlloc: try to fail more gracefully when out of registers Summary: The emitError path allows the program to continue, unlike report_fatal_error. This is friendlier to use cases where LLVM is embedded in a larger program, because the caller may be able to deal with the error somewhat gracefully. Change the number of requested NOP bytes in the AArch64 and PowerPC test cases to avoid triggering an unrelated assertion. The compilation still fails, as verified by the test.
