<div>
<pre>The code added in r235483 to handle patchpoints with symbolic destinations in
X86, did so by loading the address of the symbol into a register and then
making an indirect call. This seems needlessly inefficient, instead of:
; CHECK: movabsq $_foo, %r11
; CHECK-NEXT: callq *%r11
we should just emit:
callq _foo</pre>
