[ARM/FDPIC v6 09/24] [ARM] FDPIC: Add support for taking address of nested function
In FDPIC mode, the trampoline generated to support pointers to nested
functions looks like:
.word trampoline address
.word trampoline GOT address
ldr r12, [pc, #8]
ldr r9, [pc, #8]
ldr pc, [pc, #8]
.word static chain value
.word GOT address
.word function's address
because in FDPIC function pointers are actually pointers to function
descriptors, we have to actually generate a function descriptor for
the trampoline.
