gcc.old: vax: PR port-vax/57646 patch provided by Kalvis Duckmanton [15/21]

enable use of gas(1) directives to generate the CFI table.

gcc.old: vax: PR port-vax/57646 patch provided by Kalvis Duckmanton [14/21]

Add a TARGET_INIT_BUILTINS hook (required to be able to compile gfortran)

gcc.old: PR port-vax/57646 patch provided by Kalvis Duckmanton [13/21]

Bitfield instructions will generate a reserved operand fault if the
operands are not reasonable (size > 32, position > 31 and size not
zero and field in a register). GCC generates code to test for these
conditions but in certain circumstances, the optimiser may decide
that a bitfield extraction instruction is invariant and move it
ahead of the instructions testing its arguments.

Introduce a new target hook to indicate to GCC that a bitfield
instruction may trap and update may_trap_p_1()

XXXRO: Although this patch includes diffs outside gcc/config/vax,
NFC for !TARGET_BITFIELD_MAY_TRAP_P, i.e., other than vax.

Allow 64 bit operands addressed using post-increment addressing to be negated

gcc.old: vax: PR port-vax/57646 patch provided by Kalvis Duckmanton [3/21]

Reduce expressions specifying an address of a 64 bit quantity to
a sequence of assignments to temporary variables; this allows virtual
registers to be inst antiated properly.

gcc.old: vax: PR port-vax/57646 patch provided by Kalvis Duckmanton [2/21]

Add a special case to the zero_extract instruction to handle the case
where 32 bits are requested (i.e. the entire word). When printing a mask
operand, avoid generating values that might overflow a 32 bit word.

Save %r2..%r5 in the prologue of functions which call __builtin_eh_return().
Implement the eh_return() instruction. Ensure that the CFA is correct

Compiling some files with -fPIC and -O2 ends up having global
symbols classified as local in pic mode, and that ends up with PC32
relocations "movl *psp, %rx" (/bin/sh parse.c). Treat pic code as
shared libraries to avoid classifying common initialized symbols
as local. Thanks to thorpej@ for his help.
