[PR102627] Use at least natural mode during splitting hard reg live range
In the PR test case SImode was used to split live range of cx on x86-64
because it was the biggest mode for this hard reg in the function. But
all 64-bits of cx contain structure members. We need always to use at least
natural mode of hard reg in splitting to fix this problem.
gcc/ChangeLog:
PR rtl-optimization/102627
* lra-constraints.c (split_reg): Use at least natural mode of hard reg.
gcc/testsuite/ChangeLog:
PR rtl-optimization/102627
* gcc.target/i386/pr102627.c: New test.
