[lld] Add REQUIRES: x86 where needed to tests If building lld without x86 support, tests that require that support should be treated as unsupported, not errors. Tested using: 1. cmake '-DLLVM_TARGETS_TO_BUILD=AArch64;X86' make check-lld => Expected Passes : 1406 Unsupported Tests : 287 2. cmake '-DLLVM_TARGETS_TO_BUILD=AArch64' make check-lld => Expected Passes : 410 Unsupported Tests : 1283 Patch by Joel Jones Differential Revision: https://reviews.llvm.org/D47748 llvm-svn: 334095

[llvm-objdump] -d: print `00000000 <foo>:` instead of `00000000 foo:` The new behavior matches GNU objdump. A pair of angle brackets makes tests slightly easier. `.foo:` is not unique and thus cannot be used in a `CHECK-LABEL:` directive. Without `-LABEL`, the CHECK line can match the `Disassembly of section` line and causes the next `CHECK-NEXT:` to fail. ``` Disassembly of section .foo: 0000000000001634 .foo: ``` Bdragon: <> has metalinguistic connotation. it just "feels right" Reviewed By: rupprecht Differential Revision: https://reviews.llvm.org/D75713

[X86InstPrinter] Change printPCRelImm to print the target address in hexadecimal form ``` // llvm-objdump -d output (before) 400000: e8 0b 00 00 00 callq 11 400005: e8 0b 00 00 00 callq 11 // llvm-objdump -d output (after) 400000: e8 0b 00 00 00 callq 0x400010 400005: e8 0b 00 00 00 callq 0x400015 // GNU objdump -d. The lack of 0x is not ideal because the result cannot be re-assembled 400000: e8 0b 00 00 00 callq 400010 400005: e8 0b 00 00 00 callq 400015 ``` In llvm-objdump, we pass the address of the next MCInst. Ideally we should just thread the address of the current address, unfortunately we cannot call X86MCCodeEmitter::encodeInstruction (X86MCCodeEmitter requires MCInstrInfo and MCContext) to get the length of the MCInst. MCInstPrinter::printInst has other callers (e.g llvm-mc -filetype=asm, llvm-mca) which set Address to 0. They leave MCInstPrinter::PrintBranchImmAsAddress as false and this change is a no-op for them. Reviewed By: jhenderson Differential Revision: https://reviews.llvm.org/D76580
