Nico Weber 1813ec797d Add more test coverage for the Objective-C deprected selector warning.
I broke this case in a local patch I'm writing, and there was no test to stop
me.  Now there is.

Evgeniy Stepanov 05dc4be0dc [asan] Allow enabling coverage at activation.
This is a re-commit of r224838 + r224839, previously reverted in r224850.
Test failures were likely (still can not reproduce) caused by two lit tests
using the same name for an intermediate build target.

Craig Topper ee9eef2fd8 Teach disassembler to handle illegal immediates on (v)cmpps/pd/ss/sd instructions. Instead of rejecting we'll just generate the _alt forms that don't try to alter the mnemonic. While I'm here, merge some common code in the Instruction printers for the condition code replacement and fix the mask on SSE to be 3-bits instead of 4.

Hal Finkel 0c505b08a5 [PowerPC] [FastISel] i1 constants must be zero extended
When materializing constant i1 values, they must be zero extended. We represent
i1 values as [0, 1], not [0, -1], in i32 registers. As it turns out, this code
path was dead for i1 values prior to r216006 (which is why this did not manifest in
miscompiles until recently).

Fixes -O0 self-hosting on PPC64/Linux.

Dmitry Vyukov bda655004e tsan: fix trace initialization during thread id reuse
The current code leaves the first event in the trace part uninitialized
(from the previous thread). It can cause unpredictable behavior
during stack/mutexset restoration.
Initialize the first event to a fake harmless memory access.

Simon Atanasyan e473df2bf6 [Mips] Replace stderr output by the `llvm_unreachable` call
If a regular symbol has microMIPS-bit we need to stop linking. Now the
LLD does not check the `applyRelocation` return value and continues
linking anyway. As a temporary workaround use the `llvm_unreachable`
call to stop the linker.

Saleem Abdulrasool 747ec2dda3 MC: address some comments in deprecation checks
Bob Wilson pointed out the unnecessary checks that had been committed to the
instruction check predicates.  The check was meant to ensure that the check was
not accidentally applied to non-ARM instructions.  This is better served as an
assertion rather than a condition check.
