strcpy arg optimised out

For functions that return an argument unchanged, like strcat,
find_call_crossed_cheap_reg attempts to find an assignment between
a pseudo reg and the arg reg before the call, so that uses of the
pseudo after the call can instead use the return value.  The exit
condition on the loop looking at previous insns was wrong.  Uses of
the arg reg don't matter.  What matters is the insn setting the arg
reg as any assignment involving the arg reg prior to that insn is
likely a completely unrelated use of the hard reg.

rs6000: Fix split of ashdi3_extswsli_dot for memory (PR71670)

The splitter for ashdi3_extswsli_dot for cr0 with memory uses emit_insn
gen_ashdi3_extswsli_dot, which does not work because that emits a scratch,
while the splitter runs after reload so there should be a real register

Call tls_get_addr via GOT for GNU TLS if possible

There are extensions to x86-64 psABI:

https://groups.google.com/forum/#!topic/x86-64-abi/de5_KnLHxtI

and i386 psABI:

https://groups.google.com/forum/#!topic/ia32-abi/awsRSvJOJfs

to call tls_get_addr via GOT.  X86 assembler and linker in binutils 2.27
implemented

call *__tls_get_addr@GOTPCREL(%rip)

in 64-bit and

call *___tls_get_addr@GOT(%reg)

in 32-bit to access global and local thread loal variables in shared
library.  We check if 32-bit x86 assembler and linker work with

call *___tls_get_addr@GOT(%reg)

as 32-bit and 64-bit assembler and linker are enabled togther.

In 32-bit, since any integer register except EAX, which is used to pass
parameter to ___tls_get_addr, and ESP, can be used as GOT base, a new
register class, TLS_GOTBASE_REGS, along with a new constraint, Yb, are
added.  They are used to improve register allocation for 32-bit dynamic
TLS patterns.
