Account for inline assembly instructions in inlining cost. (#146628)
Inliner currently treats every "call asm" IR instruction as a single
instruction regardless of how many instructions the inline assembly may
contain. This may underestimate the cost of inlining for a callee
containing long inline assembly. Besides, we may need to assign a higher
cost to instructions in inline assembly since they cannot be analyzed
and optimized by the compiler.
This PR introduces a new option `-inline-asm-instr-cost` -- set zero by
default, which can control the cost of inline assembly instructions in
inliner's cost-benefit analysis.
