Upgrade the bundled PCRE to 8.32

Changelog: http://pcre.org/changelog.txt

Amongst other things, the Unicode tables were upgraded to 6.2.0
and case folding support was added, which also fixes a QString
autotest (marked as XFAIL).

Qt still requires 8.30, not 8.32.

    Feature detection (boolean) macros:
    SLJIT_32BIT_ARCHITECTURE : 32 bit architecture
    SLJIT_64BIT_ARCHITECTURE : 64 bit architecture
-   SLJIT_WORD_SHIFT : the shift required to apply when accessing a sljit_w/sljit_uw array by index
-   SLJIT_FLOAT_SHIFT : the shift required to apply when accessing a double array by index
+   SLJIT_WORD_SHIFT : the shift required to apply when accessing a sljit_sw/sljit_uw array by index
+   SLJIT_DOUBLE_SHIFT : the shift required to apply when accessing a double array by index
    SLJIT_LITTLE_ENDIAN : little endian architecture
    SLJIT_BIG_ENDIAN : big endian architecture
    SLJIT_UNALIGNED : allows unaligned memory accesses for non-fpu operations (only!)
    SLJIT_INDIRECT_CALL : see SLJIT_FUNC_OFFSET() for more information
+   SLJIT_RETURN_ADDRESS_OFFSET : a return instruction always adds this offset to the return address
 
    Types and useful macros:
-   sljit_b, sljit_ub : signed and unsigned 8 bit byte
-   sljit_h, sljit_uh : signed and unsigned 16 bit half-word (short) type
-   sljit_i, sljit_ui : signed and unsigned 32 bit integer type
-   sljit_w, sljit_uw : signed and unsigned machine word, enough to store a pointer (same as intptr_t)
+   sljit_sb, sljit_ub : signed and unsigned 8 bit byte
+   sljit_sh, sljit_uh : signed and unsigned 16 bit half-word (short) type
+   sljit_si, sljit_ui : signed and unsigned 32 bit integer type
+   sljit_sw, sljit_uw : signed and unsigned machine word, enough to store a pointer
+   sljit_p : unsgined pointer value (usually the same as sljit_uw, but
+             some 64 bit ABIs may use 32 bit pointers)
+   sljit_s : single precision floating point value
+   sljit_d : double precision floating point value
    SLJIT_CALL : C calling convention define for both calling JIT form C and C callbacks for JIT
    SLJIT_W(number) : defining 64 bit constants on 64 bit architectures (compiler independent helper)
