[X86] Merge adjacent stack adjustments in eliminateCallFramePseudoInstr (PR27140)
For code such as:
void f(int, int);
void g() {
f(1, 2);
}
compiled for 32-bit X86 Linux, Clang would previously generate:
subl $12, %esp
subl $8, %esp
pushl $2
pushl $1
calll f
addl $16, %esp
addl $12, %esp
retl
This patch fixes that by merging adjacent stack adjustments in
eliminateCallFramePseudoInstr().
