Evan Cheng	e0c5313493	Coalescer should not delete extract_subreg, insert_subreg, and subreg_to_reg of physical registers. This is especially critical for the later two since they start the live interval of a super-register. e.g. %DO<def> = INSERT_SUBREG %D0<undef>, %S0<kill>, 1 If this instruction is eliminated, the register scavenger will not be happy as D0 is not defined previously.

Coalescer should not delete extract_subreg, insert_subreg, and subreg_to_reg of

physical registers. This is especially critical for the later two since they
start the live interval of a super-register. e.g.
%DO<def> = INSERT_SUBREG %D0<undef>, %S0<kill>, 1
If this instruction is eliminated, the register scavenger will not be happy as
D0 is not defined previously.
This fixes PR5055.
