Kewen Lin d496134a6b IFN/optabs: Support vector load/store with length 
This patch is to add the internal function and optabs support for
vector load/store with length.

For the vector load/store with length optab, the length item would
be measured in lanes by default.  For the targets which support
length measured in bytes like Power, they should only define VnQI
modes to wrap the other same size vector modes.  If the length is
larger than total lane/byte count of the given mode, the behavior
is undefined.  For the remaining lanes/bytes which isn't specified
by length, they would be taken as undefined value.

/* This file specifies a list of internal "functions". These functions
differ from built-in functions in that they have no linkage and cannot
be called directly by the user. They represent operations that are only
synthesised by GCC itself.
Internal functions are used instead of tree codes if the operation
and its operands are more naturally represented as a GIMPLE_CALL
than a GIMPLE_ASSIGN.
Each entry in this file has one of the forms:
DEF_INTERNAL_FN (NAME, FLAGS, FNSPEC)
DEF_INTERNAL_OPTAB_FN (NAME, FLAGS, OPTAB, TYPE)
DEF_INTERNAL_SIGNED_OPTAB_FN (NAME, FLAGS, SELECTOR, SIGNED_OPTAB,
UNSIGNED_OPTAB, TYPE)
DEF_INTERNAL_FLT_FN (NAME, FLAGS, OPTAB, TYPE)
DEF_INTERNAL_INT_FN (NAME, FLAGS, OPTAB, TYPE)
where NAME is the name of the function, FLAGS is a set of
ECF_* flags and FNSPEC is a string describing functions fnspec.
DEF_INTERNAL_OPTAB_FN defines an internal function that maps to a
direct optab. The function should only be called with a given
set of types if the associated optab is available for the modes
of those types. OPTAB says what optab to use (without the trailing
"_optab") and TYPE categorizes the optab based on its inputs and
outputs. The possible types of optab are:
- mask_load: currently just maskload
- load_lanes: currently just vec_load_lanes
- mask_load_lanes: currently just vec_mask_load_lanes
- gather_load: used for {mask_,}gather_load
- len_load: currently just len_load
- mask_store: currently just maskstore
- store_lanes: currently just vec_store_lanes
- mask_store_lanes: currently just vec_mask_store_lanes
- scatter_store: used for {mask_,}scatter_store
- len_store: currently just len_store
- unary: a normal unary optab, such as vec_reverse_<mode>
- binary: a normal binary optab, such as vec_interleave_lo_<mode>
- ternary: a normal ternary optab, such as fma<mode>4
- cond_binary: a conditional binary optab, such as cond_add<mode>
- cond_ternary: a conditional ternary optab, such as cond_fma_rev<mode>
- fold_left: for scalar = FN (scalar, vector), keyed off the vector mode
- check_ptrs: used for check_{raw,war}_ptrs
DEF_INTERNAL_SIGNED_OPTAB_FN defines an internal function that
maps to one of two optabs, depending on the signedness of an input.
SIGNED_OPTAB and UNSIGNED_OPTAB are the optabs for signed and
unsigned inputs respectively, both without the trailing "_optab".
SELECTOR says which type in the tree_pair determines the signedness.
DEF_INTERNAL_FLT_FN is like DEF_INTERNAL_OPTAB_FN, but in addition,
the function implements the computational part of a built-in math
function BUILT_IN_<NAME>{F,,L}. Unlike some built-in functions,
these internal functions never set errno.
DEF_INTERNAL_INT_FN is like DEF_INTERNAL_OPTAB_FN, but in addition
says that the function extends the C-level BUILT_IN_<NAME>{,L,LL,IMAX}
group of functions to any integral mode (including vector modes).
Each entry must have a corresponding expander of the form:
void expand_NAME (gimple_call stmt)
where STMT is the statement that performs the call. These are generated
automatically for optab functions and call out to a function or macro
called expand_<TYPE>_optab_fn. */
