2bab197bc8 Avoid generating tempfile(s) never used
As DejaGNU is deprecated, it seems pipe-jam issue doesn't exist any more.

4af0f5fecb Revert "Don't check liveness of unallocatable registers."
The ARM target depends on CPSR liveness being tracked after register
allocation.

eeb57c7701 Don't check liveness of unallocatable registers.
This includes registers like EFLAGS and ST0-ST7. We don't check for
liveness issues in the verifier and scavenger because registers will
never be allocated from these classes.

While in SSA form, we do care about the liveness of unallocatable
unreserved registers. Liveness of EFLAGS and ST0 neds to be correct for
MachineDCE and MachineSinking.

9eb36758ac test/CodeGen/X86/vector.ll: Tweak temporary output to appease Win32 hosts.
With Lit (not bash) in a test, multiple redirects >%t might open(%t, "w") multiple. It can be avoided if latter redirect is >>%t.

It might work even if ">/dev/null" were used.

ae3a0be92e Split the Add, Sub, and Mul instruction opcodes into separate
integer and floating-point opcodes, introducing
FAdd, FSub, and FMul.

For now, the AsmParser, BitcodeReader, and IRBuilder all preserve
backwards compatability, and the Core LLVM APIs preserve backwards
compatibility for IR producers. Most front-ends won't need to change
immediately.

This implements the first step of the plan outlined here:

f8eac02fc1 Help DejaGnu avoid pipe-jam by producing less output from certain test cases.
When a test fails with more than a pipeful of output on stdout AND stderr, one
of the DejaGnu programs blocks. The problem can be avoided by redirecting
stdout to a file.
